Rear Right Hand Thread Wheel Nut is used to secure a wheel on a vehicle. Wheel nut is one rounded or conical end, used on steel and most aluminium wheels. A set of lug nuts is typically used to secure a wheel to threaded wheel studs and thereby to a vehicle's axles. Some designs use lug bolts instead of nuts, which screw into a tapped hole in the wheel's hub or drum brake or disc. This configuration is commonly known as a bolted joint.
