lug nuts
Tire mounting hardware
Lug nuts are the heavy nuts that secure a wheel to a vehicle's axle.
They thread onto bolts or studs and must be tightened in a specific pattern to ensure even pressure.
Changing a tire requires loosening all the lug nuts, and losing one while driving can be dangerous: I heard a rattling and realized I was missing a lug nut.
