A ratchet wrench, also known as a ratchet or socket wrench, is a hand tool used for tightening or loosening nuts and bolts. It is designed to provide torque in a controlled and efficient manner. Ratchet wrenches are widely used in automotive repair, mechanical work, construction, and various other applications. A ratchet wrench consists of a handle, a ratcheting mechanism. The handle provides a grip for the user to hold and apply force. The ratcheting mechanism is located inside the handle and allows for forward and backward motion without having to lift and reposition the wrench on the fastener.
