THE CHALLENGE
FOR TIGHTENING AND SECURING BOLTED ASSEMBLIES IN CRITICAL APPLICATIONS
Literally billions of bolts hold our modern society together. Because of its design, it has an unfortunate weakness: it can loosen.
THE SOLUTION
NORD-LOCK WASHERS PREVENT BOLTS FROM LOOSENING
Nord-Lock washers cannot loosen inadvertently, as a cam effect is created under the bolt/nut head. They are recognized worldwide for their ability to secure bolted assemblies exposed to strong vibrations and dynamic loads.
Nord-lock solutions consist of a pair of washers for maximum safety.
How does it work?
Because the angle of the cam 'α' is greater than that of the thread pitch 'β', a cam effect is produced which secures the fastener against loosening by rotation, even under the harshest conditions.
