Torque wrenches differ in the size of the lever, creating the maximum applied hardening, and the size of the square for the interchangeable head. Thus, keys with limits ranging from 5 to 25 Nm and finishing from 140 to 2000 Nm are produced according to the limits of the installation of tightening hardening.
