What is the importance of proper bolt torque?

Accurate bolt torque ensures optimal performance of the bolt. Too little torque may cause the bolt to get loose, and too much torque may strip the threads or break the bolt. Inaccurate torque of a single bolt may lead to failure of the entire apparatus.

Mechanics safely and efficiently install bolts using torque wrenches, torque charts, torque testers and torque sensors. Motorists typically use simple tools to change flat tires on roadsides, and carefully drive to tire shops to have a professional examine and adjust the lug nuts and bolts. Without precision torque, the bolts could fail and contribute to a dangerous accident if the tire flies off the wheel.
