All data included in this chart is advisory only and its use by anyone is voluntary. Under/over tightening of fasteners can result in costly equipment failure or personal injury. Torque is only an indirect indication of tension. *Yield strength used to calculate torque values are based on the typical yield.*ĬAUTION: Care should be used when applying a formula for torque/tension relationships. The percentages provided are illustrative of what one might expect to see should only be used as a general guide. NOTE: The actual clamp load is dependent on a variety of factors including the material, condition of the fasteners, surface finish, lubrication etc. Below are guides that show these calculations for a variety of materials, bolts sizes and thread counts over a range of frictional conditions. 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. 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. Torque is applied to the fastener in an effort to elastically deform the bolt shank.
