Lug nut
01
a small metal nut that secures a wheel to a vehicle
What is a "lug nut"?
A lug nut is a small but strong fastener that holds a wheel onto a vehicle. It is screwed onto the bolts of the wheel hub, keeping the wheel securely attached to the axle. Lug nuts are typically made of metal and are designed to withstand the pressure and force of driving. They need to be tightened properly to ensure the wheel stays in place and should be checked regularly for safety. When changing a tire, lug nuts must be loosened and then tightened again after the new tire is in position.
Examples
Make sure to tighten each lug nut securely when changing a flat tire.
The mechanic replaced the old lug nuts with shiny new ones to improve the car's appearance.
