Nord-Lock Wheel Nut

The Nord-Lock wheel nut effectively eliminates unintentional loosening of wheel nuts.

• Suits standard flat-faced steel rims; M22x1.5 studs
• Maintains 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 '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
• Once tightened, the Nord-Lock wheel nut cannot loosen by itself
