Residual Torque is the torque required to cause the threads of a fastener, such as bolt, on which torque is applied to move relative to the mating thread.

Torque Density measures the torque-carrying capability of a component in a given weight and space envelope, expressed in units of Joules per cubic meter (International System of Units) or foot-pounds per cubic foot.
