The Nord-Lock original washers

Nord-Lock wedge-locking products are recognized around the world for their ability to secure bolted joints exposed to severe vibration and dynamic loads.

The system comprises of a pair of lock washers that has cams on one side and radial teeth on the opposite side.

The system cannot loosen unintentionally as it creates a wedge underneath the bolt head/nut.

The key is the difference in angles. Since the cam angle " α " is larger than the thread pitch " β ", the pair of wedge lock washers expand more than the corresponding pitch of the thread.

We are the official distributor of NORD-LOCK products in the territory of the Republic of Belarus.
