NORD-LOCK^®

Nord-Lock®’s original wedge-locking technology represents one of the most significant advancements in industrial fastening. Designed to keep bolts firm and secure even under extreme vibration and dynamic loads, these washers replace friction with tension, ensuring a reliable and long-lasting joint.

The system consists of a pair of washers with cams on one side and radial serrations on the other. When tightened, the serrations lock into the contact surfaces while the cams create a wedge effect that prevents any movement or loosening of the bolt or nut.

Thanks to this intelligent geometry, joints remain stable, secure, and maintenance-free, even in the most demanding industrial environments.
