Wedge locking wheel nut - m22 x 1.5 - carbon steel - zinc flake coated - pkg of 20 - nord-lock 2638 the nord-lock wheel nut safely secures wheels on on-road and off-road heavy vehicles by maintaining high clamping force even under extreme operating conditions. When assembled correctly the nord-lock wheel nut cannot loosen by itself. It represents a simple and cost effective way to make wheels safe and secure for more productive and efficient operations. The nord-lock wheel nut is designed for flat-faced steel rims. The nord-lock wheel nut is based on the same principle as the nord-lock washers. Each nut incorporates a pair of captivated washers with cam faces on one side with a cam angle 'alpha' greater than the thread pitch 'beta'. 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.
