Method /principle

Nord-Lock consists of two identical wedge-locking washers, featuring radial cogs on one side, which press positively into the mating surface, and wedged cogs on the other, which increase the preload force under vibration.

Applications

The use of Nord-Lock washer pairs is beneficial wherever there is a risk of a threaded connection working loose.
Even under strong vibrations and dynamic loads, Nord-Lock guarantees maximum anti-rotation locking since over 30 years.

- Optimal locking solution under strong vibrations and dynamic loads
- Well-established locking system for threaded connections
- Can be used with screws/nuts of all property classes (up to 12.9)
