Cordless Impact Wrench: How Much Torque Is Needed?
A wrench is a hand tool developed for tightening and unscrewing of the threaded connections of the bolts and nuts. They are meant to be used in the maintenance operations and car repairs, industrial equipment, at building objects, and also in any other cases when high torque is required. The best cordless impact wrench creates an additional force during rotation. It has a hammer in its construction, which creates an additional angular impulse in a continuous mode during the resistance to rotation. Usually, the hammer is located directly on the shaft in most of impact wrenches.
