lug nut

lug nut
One of several nuts which hold the wheel and tire assembly on the car and are screwed on the studs. The inner face of the lug nut is a tapered (conical) nut to help center the wheel. On modern wheels for passenger cars, lug nuts and corresponding studs are less frequently used than bolts. On commercial vehicles, however, lug nuts are very common. A lug wrench is necessary to remove the nuts. The British term is wheel nut.
