It threads onto the spindle to secure the wheel hub assembly in place, replacing the traditional double-nut and lock ring setup with a single, integrated locking feature. Replacement is typically done when servicing wheel bearings, if the original nut is damaged, or when converting to a unitized bearing system. The nut measures 4.86 inches across the flats and is 0.5 inches thick with a 3.5-12 thread.
