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/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.
