Product Details
The Wedge Locking Wheel Nut - M22 x 1.5 is made from carbon steel and features a zinc flake coating, packaged in quantities of 20 as Nord-Lock 2638. This wheel nut is specifically designed to securely fasten wheels on both on-road and off-road heavy vehicles, maintaining a high clamping force even under extreme operating conditions. When properly assembled, the Nord-Lock wheel nut cannot loosen on its own, offering a simple and cost-effective solution for ensuring wheel safety and security, which enhances operational productivity and efficiency. It is intended for use with flat-faced steel rims and incorporates a unique design based on the Nord-Lock washers, featuring a pair of captivated washers with cam faces on one side, having a cam angle 'alpha' greater than the thread pitch 'beta.' On the opposite side, radial teeth are present, and when the wheel nut is tightened, these teeth grip the mating surfaces to lock them in place, allowing movement only across the cam faces, while the wedge effect of the cams prevents any rotation of the wheel nut.
