The Charts Below Show The Ideal Tightening Torque For Each Bolt Grade For A Variety Of Sizes.

Bolt head/wrench size to bolt diameter conversion chart: Coefficient factor indicates bolt condition (k factor indicates dry, vs lubed, vs greased, etc), koken chart is based The bolt’s class indicates its material strength, with higher numbers meaning higher tensile and yield strength.
