Torque is related to friction and diameter. torque usually is done to achieve a preload stress in the bolt of 50% of its ultimate strength
For unlubricatd bolts,
T= 0.2DP where D = diamter and P = bolt preload and T = torque
Bolt preload stress = P/A where A is stress area of bolt
#12 = 0.216 inch diameter, A = 0.024
For standard steel bolts of 80,000 psi strength,
P = 1920/2 = 960 pounds
T = 41 inch pounds
For high strength bolts of 160,000 psi strength,
T = 82 inch pounds
If bolts are lubricated, use
T = 0.15DP
T = 31 in lbs standard and 62 inch pounds high strength

Is bolt tensile strength in foot pounds or inch pounds?
Neither. Bolt tensile strength is in pounds per square inch. You are confusing torque with bolt strength. Typically a bolt will be torqued to stretch the bolt and preload it to about 50% of its strength. The relation between torque T and preload P is T = 0.15DP where D is bolt diameter(inch), T is inch pounds and P is pounds. Then stress is P/A where A is bolt area and this stress is 1/2 of strength. Note that torque in foot pounds is simply in lb/12, or 12 inch pounds = 1 ft lb

What are the crankshaft damper pulley bolt tightening specs on a Cat C 12 engine?
For a Caterpillar C12 engine, the crankshaft damper pulley bolt tightening specifications typically require a torque of around 200 ft-lbs (271 Nm). It's important to follow the specific service manual for the exact torque sequence and any additional steps, such as using a torque-to-yield approach or applying thread lubricant. Always ensure that you verify the specifications with the most current service guidelines, as they can vary by model and application.
What is the torque sequence for tightening down the valve body in a 4r44e?
The torque sequence for tightening the valve body in a 4R44E transmission typically follows a crisscross pattern to ensure even pressure distribution. Start at the center bolt and work your way outward in a spiral pattern, tightening to the manufacturer’s specified torque—usually around 10-12 ft-lbs. It's crucial to follow this sequence carefully to prevent warping or damage to the valve body. Always refer to a repair manual for the exact specifications and sequence for your specific model.
What are the torque specifications for Toyota 22RE cylinder head bolts?
Haynes manual says 58 ft lbs. be sure that the bolt threads are all clean, and if there is any resistance from putting the bolt in the hole, tap it out. the bolt size is 12 mm, pitch is 1.25. Also, make sure that there is nothing in the bolt hole. the hole in the block has oil in it, the bolt can bottom out in that and give a false torque reading.
