Lug Nut:
A lug nut is a fastener that is used to secure a wheel to the hub of a vehicle. It is typically a hexagonal or octagonal nut that is threaded onto a wheel stud which is attached to the wheel hub. Lug nuts are essential for keeping the wheels securely attached to the vehicle, ensuring safe driving conditions.
