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
