FASTENER TECH
MATERIAL SPECIFICATIONS
ARP manufactures fasteners from a wide assortment of materials ranging from popular stainless steel and 8740 chrome moly to exotic alloys that have been developed to handle space travel. You should also know that there are grades within specific alloys. For example, 8740 is available in four grades:

1. SDF (guaranteed seamless and defect free).
2 CHQ (cold head quality).
3. Aircraft.
4. Commercial. ARP uses only the first two (SDF and CHQ), e
ven though they cost more than double “Aircraft” quality
STAINLESS STEEL: Ideally suited for many automotive and marine applications because stainless is tolerant of heat and virtually impervious to rust and corrosion. ARP “Stainless 300” and Custom 450 materials are specially alloyed for extra durability. Both are polished using a proprietary process to produce a beautiful finish. Tensile STRENGTH is typically rated at 170,000-190,000 psi.

8740 CHROME MOLY: Until the development of today’s modern alloys, chrome moly was popularly considered a high STRENGTH material. Now viewed as only moderate STRENGTH, 8740 chrome moly is seen as a good tough steel, with adequate fatigue properties for most racing applications, but only if the threads are rolled after heat-treatment, as is the standard ARP production practice. Typically, chrome moly is classified as a quench and temper steel, that can be heat-treated to deliver tensile STRENGTHs between 180,000 and 210,000 psi.

ARP2000®: ARP2000 is an alloy steel that can be safely heat treated to a higher level, producing a greater STRENGTH material than 8740. While 8740 and ARP2000 share similar characteristics – ARP2000 is capable of achieving a clamp load at 220,000 psi. ARP2000 is used widely in short track and drag racing as an up-grade from 8740 chrome moly in both steel and aluminum rods. Stress corrosion and hydrogen embrittlement are typically not a problem, providing care is taken to protect the parts from moisture and the parts are kept well-oiled.

L19®: This is a premium steel that is processed to deliver superior STRENGTH and fatigue properties. L19 is a very high STRENGTH material compared to 8740 and ARP2000 and is capable of delivering a clamp load at 260,000 psi. It is primarily used in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000. Like most high STRENGTH, quench and temper steels – L19 requires special care to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture.

AERMET®: With a typical tensile STRENGTH of 290,000-310,000 psi, Aermet is a new martensitic super-alloy that is stronger and less expensive than the super-alloy austenitic materials that follow. Because it is capable of achieving incredibly high clamping loads, it is ideal for short but extreme environments like top fuel, funny car and some short track applications. Although Aermet is a maraging steel that is far superior to other high STRENGTH steels in its resistance to stress corrosion, it must be kept well-oiled and not exposed to moisture.

INCONEL 718: A nickel based material that is in the high temperature, super-alloy class, it is found to be equally suitable in lower temperature applications. This material delivers tensile STRENGTHs in the 210,000-230,000 psi range and exhibits improved fatigue properties. Best of all, Inconel 718 is completely immune to hydrogen embrittlement and corrosion.

ARP3.5® (AMS5844): While similar to Inconel 718, these super-alloys are found in many jet engine and aerospace applications where heat and stress attack the life of critical components. The high cobalt content of this alloy, while expensive, delivers a material with superior fatigue characteristics and typically tensile STRENGTH in the 260,000-280,000 psi range. The immunity to hydrogen embrittlement and corrosion of these materials is a significant design consideration. These materials are primarily used in connecting rods where extremely high loads, high RPM and endurance are important factors – Formula 1, NASCAR and IRL applications.

CUSTOM AGE 625 PLUS®: This newly formulated super-alloy demonstrates superior fatigue cycle life, tensile STRENGTH and toughness – with complete resistance to atmospheric corrosion and oxidation. ARP is the first to develop manufacturing and testing processes for fasteners with Custom Age 625+. Best of all it is less expensive and expected to soon replace MP-35 as the material of choice in the high STRENGTH, super-alloy field. Typical tensile STRENGTH is 260,000-280,000 psi.

TITANIUM: ARP now offers special order fasteners made of an alloy (Ti6Al-4V) that is specially heat-treated (a process developed by ARP’s own Russ Sherman) and provides superior STRENGTH to other titanium alloys employed in racing and aerospace. The material has a nominal tensile STRENGTH of 180,000 psi, and is very corrosion resistant. The main advantage of titanium, of course, is its weight – which is about 40% lighter than a comparable fastener made of steel. Head studs and accessory bolts are ideal applications for this lightweight material.

GENERAL TORQUE RECOMMENDATIONS
Listed here are the general torque recommendations for most ARP fasteners. Recommended torque is equal 75% of the fastener’s yield STRENGTH. Simply read down to the correct fastener size, then across to find the torque value for your application. ALWAYS LUBRICATE THE FASTENERS PRIOR TO APPLYING TORQUE TO ENSURE ACCURATE READINGS.

Note 1. The torque values represented here are intended for general information only and bulk fasteners, not for specific installations.
Note 2. On specific installations, where the supplied instructions deviate from the torque values listed here, always follow the specific instructions packaged with each kit.


Recommended Torque to Achieve Optimum Clamping Force Using ARP Lubricants - Torque (ft./lbs.) - Clamp Load (lbs.) Note: For those using Newton/meters as a torquing reference, you must multiply the appropriate ft./lbs. factor by 1.356.

PROPER FASTENER RETENTION
The importance of tightening fasteners to their required clamp load cannot be emphasized enough. If a fastener is not tightened properly, the fastener will not apply the required clamp load on the application it is being used for and may become susceptible to failure. Conversely, if a fastener is overtightened and stretched too much, it becomes susceptible to failure by exceeding the yield point. There are three generally accepted methods employed to determine how much tension is exerted on a fastener:
A. Using a torque wrench
B. Measuring the amount of stretch
C. Torque angle: rotating the fastener a predetermined amount Of these methods, measuring the amount of stretch of a fastener has been proven to be the most accurate. However, since stretch can only be measured with the use of specialty type gauges or expensive ultra-sonic measuring equipment, it is only practical for measuring the stretch on connecting rod bolts and other fasteners, where it is possible to monitor the overall length of a fastener, as it is being tightened. Since most fasteners are installed in blind holes and can’t be accessed from both ends to monitor stretch, one will most likely use a torque wrench or torque angle monitoring device for the majority of assembly work.
The Stretch Factor It is important to note that in order for a fastener to function properly it must be stretched a specific amount. The material’s ability to “rebound” like a spring is what provides the clamping force. If you were to simply finger-tighten a bolt there would be no clamp load. However, when you apply torque or rotate a fastener a specific amount and stretch it, you will be applying clamping force. The amount of clamp load a fastener will generate depends on the thread diameter, fastener material and the material’s mechanical properties, such as tensile STRENGTH and ductility. When a fastener is torqued or stretched beyond its capability the fastener material will yield. The yield point or yield STRENGTH of a fastener is the point at which the fastener has been overtightened and stretched too much, and will not return to its original manufactured length. As a rule of thumb, if you measure a fastener and it is .001½ or more, longer than its original length it has been compromised and must be replaced.

Another factor that must be considered is heat! Heat, primarily in aluminum, is another problem area. Because the thermal expansion rate of aluminum is far greater than that of steel it is possible to stretch a fastener beyond yield as the aluminum expands under heat. Thermal expansion can be offset by designing a fastener that is more flexible and installing the fastener at a safe percentage of yield.
The Stretch Gauge
We highly recommend using a stretch gauge when installing
rod bolts and other fasteners, where it is possible to measure the
length of the fastener. It is the most accurate way of measuring
clamp load of any bolt. Simply follow manufacturer’s instructions

of the fastener length prior to installation and after any disassembly.
If there is a permanent increase of .001½ or more in length,
there is a deformation and the bolt should be replaced. A sample
stretch monitoring chart is located on page 30.
Using A Torque Wrench
There are a number of things to consider when using a torque
wrench. The “friction factor” changes from one cycle to the next.
That is, friction is at its highest value when the fastener is first
tightened. Each subsequent time the fastener is torqued and loosened,
the amount of friction reduces. Eventually the friction levels
out and becomes fairly consistent for all following repetitions.

Three basic elements that contribute to the friction factor:
1. Most importantly - the fastener assembly lubricant
2. The condition of the threads
3. The surface finish of the fastener
Because of these variables, a phenomenon known as clamp
load scatter occurs. Clamp load scatter is the variation in clamp
load a fastener generates due to fluctuating levels of friction from
one torque cycle to subsequent cycles. It’s not uncommon to see
clamp load scatter in the range of 4,000-8,000 pounds between
the first and tenth pull on a new fastener depending on the
lubricant used.


Page 29
The Lubricant Is The Key
A major factor that influences friction in a fastener is the
lubricant used, and therefore influences the torque required for
a particular installation. One of the most overlooked aspects of
choosing a fastener assembly lubricant is…the lubricant’s ability
to stabilize friction inherent in all high performance engine
fasteners. As discussed earlier, friction is at its highest point
when a new fastener is first tightened. This friction inhibits the
fasteners ability to achieve the required clamp load on the first
several cycles. In fact, ARP’s in-house Research and Development
department has proven that new fasteners using motor oil and
other commonly used lubricants such as Moly and EPL typically
require 5-7 cycles before final torquing to level out the initial friction and achieve the required clamp load. Slicker lubricants may
reduce the required torque by as much as 20-30% to achieve the
desired clamp load, but compromise in areas of major importance
such as repeatability, and may yield the fastener prematurely.
Typically, the slicker the lubricant, the greater the clamp load
scatter will be during installation.

The bottom line: clamp load repeatability and consistency
from a fastener to fastener perspective, should be the number
one consideration when choosing a fastener assembly lubricant.
Remember even the best fastener is only as good as its installation.
Clamp load repeatability is the foundation for maintaining
round housing bores, and consistency ensures the same clamp
load from one fastener to another across a large area, such as the
deck surface of a cylinder block. These two fundamentals are the
cornerstone of every successful fastener installation and that’s
why ARP’s engineering team set out to develop the “ultimate”
fastener lubricant. The result of several years of extensive R&D is
a remarkable assembly lube called ARP Ultra-Torque®. As shown in the graph above, ARP Ultra-Torque® clearly provides the clamp load repeatability and consistency that no other fastener assembly lubricant on the market today can provide.

Fastener Surface Finish and Condition of Threads

In addition to the lubricant used, friction is affected by the surface
finish of the fastener itself and the condition of the threads.
For example, black oxide behaves differently than a polished
fastener so it’s important to follow the torque recommendations
with each fastener kit. Then there’s the very real problem of
burrs and debris in the bolt holes that can significantly affect the
amount of torque required to achieve the recommended clamp
load. All bolt holes should be thoroughly cleaned using thread
chasers to clean the threads before installation. ARP offers these
special cleaning chaser taps on page 136.

Torque Wrench Accuracy It is possible for even the most expensive torque wrenches to lose accuracy over time. Rough use or repeated loosening of fasteners using your torque wrench as a “breaker bar” will exacerbate the loss of accuracy. In fact, ARP field technicians have seen a wide range of torque wrench reading errors as much as 15-30%. This just emphasizes the importance of treating torque wrenches with the utmost of respect and having them checked periodically for accuracy.

The Torque Angle Method
Since the amount that a bolt or nut advances on the thread per degree of rotation is determined by the thread pitch, it would appear that any amount of stretch in a given bolt or stud can be accurately predicted by measuring the degrees of turn from the point where the underside of the bolt head or nut face contacts the work surface. Termed the “torque angle” method, this procedure has long been the standard of civil engineering. It has been suggested that torque angle is a relatively simple and valid procedure to use in blind hole installations—where it is not possible to physically measure the actual bolt stretch.
ARP has conducted extensive evaluations of the torque angle
method, and concluded that – for high performance engine applications
– it is suitable only when calibrated for each installation.
Our investigation has proven that installed stretch is dependent not only on the pitch of the thread and the degree of rotation, but also on the amount of compression of the clamped components, the type of lubrication, the length of the male fastener, and the amount of engaged thread. It’s important to note that for the same degree of rotation, the amount of bolt stretch will differ from aluminum to cast iron cylinder heads, or when installing a steel main cap on a cast iron or aluminum block. Furthermore, each length fastener requires a unique torque-angle to obtain the correct stretch for that fastener. The torque angle method can be accurate – but only if each individual application has been calibrated by direct measurement of bolt stretch. If you do employ the torque angle method, it’s best to begin calibrating rotation from some small measured torque rather than the first point of contact with the work face. To achieve optimum accuracy, always use ARP

THE IMPORTANCE OF PROPER
ROD BOLT STRETCH/TORQUE…
Whether measured by stretch or by torque, properly installing
a rod bolt is essential for trouble-free performance. If a bolt is
installed without sufficient clamp load, every revolution of the
crankshaft will cause a separation between the connecting rod and
rod cap. This imposes additional stretch in the bolt. The stretch
disappears when the load is removed on each revolution, or cycle.
Over time, this cycle stretching and relaxing can cause the bolt
to fail due to fatigue, just like a paper clip that is bent back and
forth by hand. To prevent this condition, the bolt’s clamp load
must be greater than the load caused by rotating assembly reaching
top dead center.
A properly installed rod bolt remains stretched by its clamp
load and is not subjected to the cyclic loads imposed on the
connecting rod. A quality bolt will stay stretched this way for
years without failing. The important thing is to prevent the bolt
from failing due to fatigue by tightening it to a load greater than
the demand of the engine. Protect your bolts – tighten them as
recommended.
You can measure the actual stretch of rod bolts through use
of a stretch gauge, or a micrometer for that matter. Prior to
installing the rod, measure the length of the bolt in an untorqued
state. Write this length down. You can make a chart similar to
the one shown on this page to keep track of the data. When you
tear the engine down for maintenance, again measure the length
of each rod bolt – being careful to keep everything in the proper
order. If any of the rod bolts have taken a permanent set and
have stretched by .001½ or longer you should replace the fastener
IMMEDIATELY! The stretching is a sure indicator that the bolt
has been compromised and taken past its yield point.
In other types of bolted joints, this careful attention to
tightening is not as important. For example, flywheel bolts need
only be tightened enough to prevent them from working loose.
Flywheel loads are carried either by shear pins or by side loads
in the bolts; they don’t cause cyclic tension loads in the bolts.
Connecting rod bolts, on the other hand, support the primary
tension loads caused by engine operation and must be protected
from cyclic stretching. That’s why proper tightening of connecting
rod bolts is so important. See pages 25-27 for recommended
stretch and torque values.

Friction is a challenging problem because it varies so much,
and is extremely difficult to control with most commonly known
lubricants. The best way to avoid the pitfalls of friction and the
known variables associated with different lubricants is by using
the stretch method. By using the stretch method and removing
the friction variable, clamp load can be controlled and repeated.
Each time a new bolt is torqued and loosened, the friction factor
gets smaller. Eventually the friction levels out and becomes constant
for all following repetitions, making it necessary to tighten
and loosen a new bolt several times before final installation,
when the stretch method cannot be used. The number of cycles
depends on the lubricant. Most lubricants require, 5-7 tightening
and loosening cycles to level out the friction before final installation.
However, with the introduction of ARP’s new Ultra-Torque
fastener assembly lubricant, cycling a new fastener before final
installation becomes a “thing of the past.” See page 134 for more
information on ARP Ultra-Torque® fastener assembly lubricant.

A rod bolt stretch gauge is one of the most important tools a serious
engine builder can own. It’s valuable in properly setting up a rod for
resizing, obtaining the proper clamp load when installed.

PRO SERIES CONNECTING ROD BOLTS
A large number of connecting rod manufacturers
have chosen ARP bolts as standard equipment.
They’re proud to advertise their products as being
equipped with ARP rod bolts. And for good
reason. The “weak link” in a connecting rod has
always been the bolt, and racers know that nobody
builds a better bolt than ARP. However, it is critically
important to monitor the stretch of each bolt
and replace it when it has permanently elongated
by .001½. Below you will find an extensive listing of
aftermarket connecting rods and replacement bolt
specifications.
In some instances, you may want to go to an
ARP rod bolt made from a better grade of material.
This will provide you with improved reliability.
However, please understand that when you want
bolts made from exotic, super high STRENGTH materials,
the cost will increase significantly. If you’re on
a budget, it’s best to go with the most cost-effective
solution. This is typically defined by the loads
that are carried by the bolts in terms of piston/
rod weight and the rotational speed of the engine.
The most cost effective design is the one in which
the bolt STRENGTH is just great enough to handle
its anticipated load – plus a safety margin for the
occasional overloads. Using a material which has
far more STRENGTH than required is not as cost effective
– but will definitely give you an extra margin
of safety and longer service life.
You should also know that ARP rod bolts
are superior to those from other manufacturers.
Especially in the area of fatigue STRENGTH. Testing
has shown ARP rod bolts to have twenty times the
fatigue STRENGTH of other bolts. In the chart below,
you’ll find a bar chart that graphically shows the
difference between ARP Pro Series rod bolts and
the fastener made by a leading competitor. It’s
easy to see why ARP bolts are superior. As such,
it makes good sense to rely on ARP for optimum
connecting rod service and reliability. Make the
most of your racing budget and rely on ARP rod
bolts. You’ll find the ARP name proudly stamped
on each bolt as your assurance of quality.

MATERIALS USED IN THE MANUFACTURE
OF CAP SCREW TYPE CONNECTING ROD BOLTS
8740 CHROME MOLY: Until the development of today’s modern alloys, chrome moly was popularly considered a high STRENGTH material. Now viewed as only moderate STRENGTH, 8740 chrome moly is seen as a good tough steel, with adequate fatigue properties for most racing applications, but only if the threads are rolled after heat-treatment, as is the standard ARP production practice. Typically, chrome moly is classified as a quench and temper steel, that can be heat-treated to deliver tensile STRENGTHs between 180,000 and 200,000 psi.
ARP2000®: ARP2000 is an alloy steel that can be safely heat treated to a higher level, producing a greater STRENGTH material than 8740. While 8740 and ARP2000 share similar characteristics – ARP2000 is capable of achieving a clamp load at 220,000 psi. ARP2000 is used widely in short track and drag racing as an up-grade from 8740 chrome moly in both steel and aluminum rods. Stress corrosion and hydrogen embrittlement are typically not a problem, providing care is taken to keep the parts well-oiled and not exposed to moisture. L19®: This is a premium steel that is processed to deliver superior STRENGTH and fatigue properties. L19 is a very high STRENGTH material compared to 8740 and ARP2000 and is capable of delivering a clamp load at 260,000 psi. It is primarily used in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000. Like most high
STRENGTH, quench and temper steels – L19 requires special care to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture.
ARP3.5® (AMS5844): While similar to Inconel 718, these super-alloys are found in many jet engine and aerospace applications where heat and stress attack the life of critical components. The high cobalt content of this alloy, while expensive, delivers a material with superior fatigue characteristics and typically tensile STRENGTH in the 260,000- 280,000 psi range. The immunity to hydrogen embrittlement and corrosion of these materials is a significant design consideration.
These materials are primarily used in connecting rods where extremely high loads, high RPM and endurance are important factors – Formula 1, NASCAR and IRL applications. CUSTOM AGE 625 PLUS®: This newly formulated super-alloy demonstrates superior fatigue cycle life, tensile STRENGTH and toughness – with complete resistance to atmospheric corrosion and oxidation. ARP is the first to develop manufacturing and testing processes for fasteners with Custom Age 625+. Best of all it is less expensive and expected to soon replace MP-35 as the material of choice in the high STRENGTH,

HOW TO: INSTALL CAP-STYLE ROD BOLTS
Replace your original connecting
rod cap screws with these ARP products
for enhanced durability and improved
STRENGTH. Use whenever cap screw-style
bolts are used for rod cap retention.

TECH TIP
Be sure the torque spec used when
re-sizing a rod and final engine assembly
are the same. Communicate with
your machinist! Use a stretch gauge
for both functions, if possible.

NOTE: One way to know if a bolt is ready
to fail is if it has permanently yielded
.001½ or more. See page 28.

3. Measure pre-torqued bolt length.
Always keep a log of the original free
standing length. A sample is on page 29.
Assemble cap to rod, then lubricate the
bolt threads and washer with ARP Ultra-
Torque lubricant. Install bolt & washer.


1. Clean and inspect all hardware for obvious
damage. If necessary, chase or re-tap
con rod threads to ensure proper thread
engagement and accurate torque readings.


4. Using a stretch gauge or micrometer to
measure fastener stretch, torque rod bolt
until recommended bolt stretch is achieved.
A rod bolt stretch and torque table is located on
pages 25-27.


2. Position the washer with the chamfer
facing the bolt head to ensure it clears the
underhead radius. NOTE: Improper installation
will cause premature bolt failure.


5. Once properly preloaded, have the rods
resized before assembling them to the
pistons, then install in engine using the
prescribed bolt-stretch method.


Page 33
HOW TO: INSTALL OEM-STYLE ROD BOLTS
Improved reliability and optimum
STRENGTH are the main attributes of ARP’s
replacement rod bolts. These are the
finest fasteners available today, and are
recommended for all high performance
applications.

TECH TIP
Be sure the torque spec used when
re-sizing a rod and final engine assembly
are the same. Communicate with
your machinist! Use a stretch gauge
for both functions, if possible.

3. Lubricate the bolt threads and the
face of the nuts with ARP Ultra-Torque
lubricant, tighten nuts to achieve recommended
bolt stretch. A rod bolt stretch and torque table is located on pages 25-27.



1. Inspect rods to ensure there is adequate
chamfer to clear radius under heads, then
install bolts after inspecting for damaged
hardware.

4. With proper preload applied, have rods
resized. This procedure is recommended
any time rod bolts are replaced.


2. Reinstall the rod cap, then measure bolt
length using a micrometer (free standing
length).

5. Install rod and piston assemblies in
engine using the prescribed bolt stretch
method or by following recommended
torque values.

Choose From Three ARP Replacement Rod Bolts:
Because factory connecting rods (or aftermarket versions of
OEM rods) are used in a variety of applications from rebuilt stock
motors to modified powerplants used in circle track, marine and
drag racing engines – including those with superchargers and/
or nitrous oxide injection systems – ARP offers replacement rod
bolts in three different models. All of them are substantially better
than the stock OEM and most aftermarket bolts.

GOOD: STANDARD HIGH PERFORMANCE BOLTS
A premium grade 8740 alloy chrome moly steel is used to
manufacture ARP High Performance connecting rod bolts.
This material is heat-treated to provide a tensile STRENGTH in
the 200,000 psi range, which is substantially stronger than
the OEM bolts. Cycle testing shows ARP High Performance
rod bolts to be nearly five times more reliable than stock bolts.

BETTER: WAVE-LOC® HIGH PERFORMANCE BOLTS
The same heat-treated 8740 chrome moly steel is used to make
these rod bolts as ARP’s standard High Performance rod bolts.
The big difference is in the shank design, with ARP’s exclusive
(and patented) Wave-Loc technology providing substantial
benefits. Because there are fairly wide tolerances in factory bolt
holes, the bolt must be able to fit snugly and a knurl is applied.
Unfortunately, these knurls cut deep into the bolt material, leaving
sharp edges and enormous “stress risers” that promote failure.
That’s why ARP developed the Wave-Loc design that features
symmetrical waves and has an effective interference range of
.001½ to .005½ for proper cap alignment.

BEST: “PRO” SERIES WAVE-LOC BOLTS
For the most severe applications, in conjunction with
aftermarket I-beam rods, ARP has developed the “Pro” Series
Wave-Loc bolts. These ultra heavy-duty rod bolts are made from
a special material designated ARP2000. It has approximately
200% the fatigue life of 8740 chrome moly steel and has a tensile
STRENGTH of 220,000 psi, and is capable of more than 12,000 lbs.
clamping force.

REPLACEMENT
CONNECTING ROD BOLTS

TECH NOTE: ROD BOLTS

Unquestionably the most important fasteners in any
engine are the connecting rod bolts, as they hold the key
to the entire rotating assembly. A broken bolt will lead to
catastrophic engine failure. As you can imagine, the most
critical joint is where the connecting rod halves mate. The
rod bolts must support the primary tension loads caused
by each rotation (or cycle) of the crankshaft. When the
crank rotates, the big end of the connecting rod essentially
becomes oval-shaped and the rod bolts bend. As the crankshaft
continues to rotate, the rod becomes round again.
With alternating tension loads and cyclic bending of the
bolts, it is very important to install fasteners that are able to
exert a clamping force greater than the load imposed upon
the joint (tension).

In addition to utilizing a rod bolt with sufficient STRENGTH
to withstand the tremendous cyclical strains placed upon
it, it is absolutely imperative that the bolts be properly
tightened. The preferred method of monitoring the correct
amount of tension is through use of a stretch gauge. This
is far more accurate than using a torque wrench. Moreover,
through subsequently checking the rod bolts length at teardowns,
it is possible to determine if it has been stressed
beyond safe limits and must be replaced.

ADVANTAGES OF WAVE-LOC ROD BOLTS:

• Wave-Loc surface contacts the rod and cap for optimum alignment and reduction of fluctuating
stress – which STRENGTHens the rod itself!
• Provides snug fit for all OEM connecting rods (interference range of .001½ to .005½), despite wide range of factory
rod bolt hole tolerances.
• Available for most applications.
• Superior material grain flow because of patented Wave-Loc surface design as compared to knurled bolts that have sharp edges and “built-in” stress risers.
• Galling and scoring of the rod is virtually eliminated because there is only smooth contact and absolutely
no “digging.”

CYLINDER HEAD STUDS
It is for good reason that virtually every top professional engine builder relies on ARP Pro Series head studs for their all-out competition powerplants. Simply stated, there’s not a better stud setup on the market today.
For openers, ARP only uses premium grade 8740 alloy and a proprietary ARP2000® alloy that are rated far superior to “aircraft” quality alloy steels. Secondly, each stud is placed vertically into special racks and precisely heat-treated to 190,000 psi for the 8740 material and 220,000 psi for the ARP2000® material. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best. Following heat-treat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight part. It’s important to note that lesser quality studs are not even centerless ground – the material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because ARP studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned – something that won’t happen with inferior quality head studs

ARP studs are thread rolled after heat-treat, which gives them about 2000% (that’s twenty times) better fatigue STRENGTH than those studs that are threaded prior to heat-treat (a very common industry practice). It costs a lot more to do it this way, because it’s tough on tooling, but the results are well worth the extra effort. You will also note that ARP offers specially undercut studs for several engines. This procedure (done only to the shorter studs) more equalizes the “stretch” of both studs, which makes for a more consistent clamping force – and one that compensates for head gasket compression when the cylinder heads are installed. This helps prevent blown head gaskets, and assures optimum engine sealing!
Premium quality 8740 and ARP2000® head stud kits are available for most domestic and import applications. You won’t find a better quality stud on the market from any other source. Look for ARP stamped on each stud as your assurance of quality. Clearly, they are the best on the market today, and the favorite of leading professional engine builders in all forms of racing.

.
HEAD STUDS vs. BOLTS...A TECHNICAL DISCUSSION
ARP’s factory Tech Representatives are often asked which
is better, cylinder head studs or bolts. The answer, invariably,
depends on the installation. On many street-driven vehicles,
where master cylinders and other items protrude into the engine
compartment, it’s probably necessary to use head bolts so that
the cylinder heads can be removed with the engine in the car.
For most applications, however, studs are recommended.
And for good reason. Using studs will make it much easier to
assemble an engine (especially a racing powerplant which must
be serviced frequently and quickly!) with the cylinder head and
gasket assured of proper alignment.


Studs also provide more accurate and consistent torque
loading. Here’s why. When you use bolts to secure the head, the fastener is actually being “twisted” while it’s being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously. A stud should be installed in a “relaxed” mode – never crank it in tightly using a jammed nut. If everything is right, the stud should be installed hand tight. Then, when applying torque to the nut, the stud will stretch only on the vertical axis. Remember, an undercut shorter stud will have a rate similar to a longer, standard shank stud. This provides a more even clamping force on the head. Because the head gasket may compress, check with your gasket manufacturer to see if retorquing is required.

HEAD STUD INSTALLATION
1. Clean and chase all bolt threads in block to ensure proper
thread engagement and accurate torque readings.
2. All hardware should be cleaned and inspected for possible
shipping damage prior to installation.
3. Since most studs extend into the water jacket, coat threads
with ARP thread sealer and screw in hand tight ONLY.
4. Install gasket and head, then lubricate the stud threads, the
washers and nuts with ARP Ultra-Torque fastener assembly
lubricant prior to their installation.
5. Following the engine manufacturer’s torque sequence,
tighten the nuts to the recommended torque value found on
the instruction sheet provided with each kit.
NOTE: To ensure positive sealing of “wet” head studs,
a hardening or semi-hardening sealant, such as Loc-Tite or
Permatex, etc. should be used. Some engine builders employ
a sealer in the coolant, such as Aluma-Seal, Silver Seal or
K&W sealer, etc. You may also use high temperature RTV
silicone. Whatever product is used, it is best if the cylinder
head is installed and torqued to proper levels BEFORE THE
SEALANT HAS CURED!

More ARP bolts coming soon.
