Grade 2, 5, and 8 values are for slightly lubricated bolts . Shop for US Hex Bolts . Notes: Values calculated using industry accepted formula T = KDP where T = Torque, K = torque coefficient (dimensionless), D = nominal diameter (inches), P = bolt clamp load, lb. K values: waxed (e.g. pressure wax as supplied on high strength nuts) = .10, hot dip galvanized = .25, and plain non-plated bolts (as received) = .20. Bolt Torque Chart. If the nut material is the limiting factor in the fastening system, then obviously increasing the material strength of the bolt will have no effect on increasing the clamping capability of the assembly. Also, if the nut material is the limiting factor, the maximum clamping capability (and corresponding bolt torque).
