Large diameter bolting presents several problems The strength of a screw fastener increases with the square of its diameter however the torque required increases with the third power Because of this bolts with a diameter greater than 1 inch cannot be
Fastener Torque Specs 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
