Nord-Lock secures threaded connections and effectively prevents spontaneous loosening, even under strong vibrations.
Nord-Lock wedge-locking washers are mechanical machine elements. They secure threaded connections under vibration by increasing the preload force rather than by friction,making them superior to conventional screw locks.
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.
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)
- Simple to detach and reusable with no performance loss
- Reliable locking element
