Definition

Noun: A lug wrench is a specialized hand tool designed for tightening or loosening the lug nuts that secure a vehicle's wheel to its axle. It is characterized by having jaws or sockets with projecting lugs (or studs) that fit into the corresponding holes or recesses on the lug nuts, allowing for the application of torque.

Usage

A lug wrench is an essential tool for changing a flat tire on a car, truck, or other vehicle. It is typically found in a vehicle's trunk or storage compartment as part of the standard emergency kit. The user fits the wrench's socket or jaw onto a lug nut and turns it, usually in a counter-clockwise direction to loosen and a clockwise direction to tighten.
