NORD-LOCK WEDGE-LOCKING SOLUTIONS

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

Developed in Sweden, in 1982, Nord-Lock washers prevent bolted connections from loosening — even under the most severe vibration and dynamic loads. With their unique wedge-locking technology and high-quality steel, the washers increase operational reliability and lower your maintenance costs, while significantly reducing the risks of unplanned production stops, accidents, and warranty claims.
