The Nord-Lock wheel nut safely secures wheels on both on-road and off-road heavy vehicles, by maintaining high clamping force, even under extreme operating conditions. It is designed for flat-faced steel rims and when assembled correctly, cannot loosen by itself.
Nord-Lock wheel nuts have been rigorously tested and approved by independent institutes as well as certification authorities.
The wheel nut represents a simple and cost effective way to make wheels safe and secure for more productive and efficient operations. Each nut incorporates a pair of captivated washers with cam faces on one side and radial teeth on the other.
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.
Prevents loosening caused by vibration and dynamic loads.
- Quick and easy to install and remove with standard tools.
- Improves driver productivity while reducing operating and service costs.
- Minimizes risk of accidents and injury.
- Suits flat faced steel rims and regular tools.
- Reusable and durable. - Prelubricated.
- Predictable preload thanks to defined and uniform friction conditions of the washers’ mating surfaces.
