Torquing involves the process of measuring a force's tendency to produce rotation and torsion about a designated axis. Efficient functioning of a threaded fastener relies upon its objective to clamp parts together with a tension greater than any separating external force. Therefore, the bolt remains under near constant stress, with immunity to fatigue. The necessary tightening torque process is imperative to ensure there is correct initial tension.
