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
What else can I help you with?
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
