Torture

A torque wrench works the same as a ratchet or spanner. The keys work like a lever to convey strength to bolts or nuts. However, a torque wrench provides a specific force that prevents the bolts or nuts from being damaged. Thanks to a torque wrench you do not tighten the nut or bolt too hard or too soft. The key gives a warning click by means of a spring and bullet. After this click, the nut or bolt is tightened.
