Wheel lug nuts are fasteners that attach the wheel to the vehicle’s hub. They come in various sizes, shapes, and styles depending on the make and model of the vehicle. Lug nuts are typically made of steel, aluminum, or other alloys and are designed to be tightened to a specific torque value using a lug wrench or a socket wrench. Some lug nuts are also designed to be used with wheel locks to provide an extra layer of security to prevent theft of the vehicle’s wheels.
