Tab. 8. Torque values for bolts
In the absence of specific torque values, the following chart can be used as a guide to the
maximum safe torque for a particular size and grade of fastener. There is no torque difference for
fine or coarse threads. Torque values are based on clean, dry threads. Reduce value by 10% if
threads are oiled before assembly.
