What are some common uses for a bolt tightening torque?

Bolt-tightening torques are most commonly used to ensure that lug nuts are tightened to a particular safety standard to prevent them from falling off and causing breakage to a piece of machinery, which could harm someone if not properly assembled. A tightening torque also prevents the stripping of metal bolts, allowing the ideal amount of pressure to ensure the job is done correctly.

Tightening torques are a form of socket wrench with a special mechanism in place to allow tightening. They were designed to prevent the tightening of bolts on water mains and steam-pressured pipes that could burst if under too much pressure from incorrect assembly.
