The Nord-Lock wheel nut is a 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 lock washers that have cam faces on one side, with a cam angle greater than the thread pitch. 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. The product is based on proven wedge-locking technology, suits flat-faced steel rims, M22x1.5 studs, and is easy to install and remove.
Conventional wheel nuts used on heavy vehicles can loosen. This unfortunate and long-standing truth has resulted in wheels dislodging and causing traffic accidents involving property damage, personal injuries and, in the worst case, fatalities. Loose wheel nuts also result in increased operating costs as well as decreased overall delivery efficiency and productivity levels. The new Nord-Lock wheel nut effectively eliminates unintentional wheel nut loosening. The product will improve safety of the vehicle, enhance productivity, prevent increased costs of fuel consumption and tire or wheel wear, and contribute to more cost-effective overall operations.
