Simple and cost effective way to make wheels safe
The Nord-Lock wheel nut safely secures wheels by maintaining high clamping force even under extreme operating conditions. Each nut incorporates a pair of captivated washers with cam faces on one side, with a cam angle ‘α’ greater than the thread pitch ‘β’. On the opposite side there are radial teeth. When the wheel nut is tightened, the teeth of the Nord-Lock washers grip and lock the mating surfaces, allowing movement only across the cam faces. Any rotation of the wheel nut is blocked by the wedge effect of the cams.
Based on proven technology
The Nord-Lock wheel nut is based on our unique wedge-locking technology, which uses tension instead of friction to secure bolted joints. The system has been used for over 25 years to ensure the structural security of bolted applications exposed to strong vibrations and high dynamic loads.
