The simple and cost effective way to make wheels safe
The Nord-Lock wheel nut safely secures wheels by maintaining a high clamp force even under severe operating conditions. Each nut incorporates a pair of washers that have cam faces on one side, with a cam angle ‘a’ greater than the thread pitch ‘ß’. 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. Once tightened, the Nord-Lock wheel nut cannot loosen by itself.
