Feb 20, 2022

A wrench is a commonly used installation and removal tool. It is a hand tool that uses the principle of leverage to turn bolts, screws, nuts and other threaded fastening bolts or nuts. Wrenches are usually made of carbon or alloy structural steel.

The wrench usually has openings or sleeve holes for holding the bolt or nut at one or both ends of the shank. When in use, an external force is applied to the shank in the direction of thread rotation to turn the bolt or nut.
