Torque testing examines the mechanical properties of metal fasteners, including the torque resistance of bolts, screws and studs. The purpose is to verify the torque resistance of bolts and nuts.
Breaking torque is the torque at which a bolt or screw is sheared off. Maximum installation torque can be understood as the maximum force that may be applied when tightening a screw during installation. The torque test is mainly applicable to bolts and screws that cannot be subjected to a tensile test.
