What is the recommended maximum torque for your bolt?
Typical maximum recommended thightening torques for metric bolts
- coarse threaded
- lightly oiled threads
- tension 85% of proof load

How to measure the torque on bolts?
The torque value of a bolt can be checked in 3 ways:
- The movement check:
- The loosening check:
- The marking check:
What are the torque values inner primary bolts?
You need a manual, as you need torque specs for the entire assembly of the primary cover, inner primary bolts, clutch hub nut, compensator, starter bolts, starter jackshaft bolt, swingarm pivot bolts and rear axle nut. What I know off the top of my head: 1.) Primary cover bolts: 14-21 ft lbs 2.) Inner primary bolts: 18-24 ft lbs
What are the torque specs for the transmission pan bolts?
pan bolt torque is in inch pounds (not a lot, around 10-15) generally it's not necessary for exact because pans are a bit warped many times and exact dosen't work anyhow. Tighten snugly without leaning into the wrench, then check running and tighten anywhere that is seeping.

1 Proofload is the published number that full size headed bolts are tested to. The bolt is stressed up to the proofload value, and if there is no deformation, elongation, or fracture, then the bolt is deemed to have passed.

How much torque is used for bolt tension?
Bolt torque provides only an indirect approximation of material stress. It is estimated that only about 10% of the tightening torque actually results in useful bolt tensioning. The remaining 90% is lost due various forms of friction that occur during the tightening process.
What is bolt proof load?
Bolt proof load is defined as the maximum force that the material can support without experiencing permanent deformation. Although material properties vary, an approximate estimate of proof strength is 85% - 90% of its yield strength.
What is a s in a bolt?
A s = Bolt Thread Tensile Stress Area (in 2)
Why is it important to test actual fastener components?
Testing of actual fastener components is recommended to determine appropriate torque values for all critical-use applications.
What is the objective of engaging threads?
The objective is to assure that the engaging threads will not strip under the loading that the bolt is able to apply.
What is the rule of thumb for threads?
A common rule-of-thumb is to provide a minimum length of thread engagement equal to the (major) diameter of the fastener.
Does increasing the strength of a bolt increase the clamping capability of the bolt?
If the nut material is the limiting factor in the fastening system, then obviously increasing the material strength of the bolt will have no effect on increasing the clamping capability of the assembly.

What is socket set screw?
Socket Set Screws are designed to be used where permanent or adjustable locations of components on shafts is required.
What is a flat socket head cap screw?
Flat socket head cap screws are designed for use in applications where the head cannot protrude above the mating parts. They are set in countersunk holes and the top of the head is flush with the surface of the assembly.
What is a button socket cap screw?
Button socket cap screws are designed for applications that allow the head to protrude above the mating parts. The curved design of the button head is decorative and protects adjoining parts from scrapes and other damage. The greater under head area also protects mating parts from damage. Due to the head design these parts should not be used in critical applications where high tensile strength is required.
What happens if you torque bolts?
If you properly torque the bolts, they will provide the maximum amount of clamping force under load. If you under torque the bolts, they can quickly come loose.
How to tell which bolt you are working with?
You can tell which bolt you are working with by the markings on the head.
What does class mean in bolts?
The class indicates the material strength of the bolt.
