Torque is applied to the fastener in an effort to elastically deform the bolt shank. In the case of bolts and nuts, this elastic deformation between the bolt head and the nut is critical in order to create tension or clamping force to hold the joint together. The amount of torque applied is a function of the frictional forces and bolt diameter and is typically calculated utilizing a clamp load equaling 60-70% of the yield. Below are guides that show these calculations for a variety of materials, bolts sizes and thread counts over a range of frictional conditions.
