Nord-Lock created the original wedge-locking technology that secures bolted joints, even when exposed to severe vibration and dynamic loads. It is impossible for our products to loosen unintentionally due to the wedge created underneath the bolt head and nut.


The Nord-Lock wheel nut range has been extended to 6 sizes, M-16-M24. This large range offers increased safety for both on-road and off-road vehicles thanks to Nord-Lock wedge-locking technology, which ensures the wheel nuts cannot loosen by themselves. Nord-Lock wheel nuts minimize the risk of accidents, improve driver productivity and reduce operating and service costs.

Wheel Nuts

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. 

Range: M16 - M24 

How it works?

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.



  • Quick and easy to install and remove with hand tools
  • Pre-lubricated
  • High corrosion resistance
  • Reliable locking
  • Reusable (depending on usage environment)

Testing & Certification

Nord-Lock wheel nuts have been rigorously tested and approved by independent institutes as well as certification authorities. The Junker test is the most rigorous method for testing change in clamp load for wheel nuts.

During the Junker test, the tested products are tightened and the clamp load is monitored during 1000 load cycles. The conventional wheel nut rotates and loses most of its initial clamp load in the joint. The Nord-Lock wheel nut safely secures the wheel joint and maintains the clamp load.
