Bolt Torque Charts. A2/A4 Stainless Steel; ISO 7380 Button Head Socket. Accepted formulae relating torque and tension, based on many tests are: M = P x D M = torque lbf.ft 60 P = bolt tension lbf D = bolt dia.ins Or for metric sizes: M = P x D M = torque N.m 5000 P = bolt tension Newtons D = bolt dia.
