Key Information

This is a critical structural fastener used to secure the wheel hub or stub axle assembly. It ensures that the wheel bearings and hub remain correctly seated and preloaded against the axle, which is essential for the safe operation of heavy machinery and commercial trucks.

Because this nut experiences significant rotational forces and stress, it is manufactured to high-strength standards to prevent loosening or failure. It is often used in conjunction with specific locking mechanisms to ensure it does not back off under vibration.
