Ever wondered how Nord-Lock washers actually prevent bolts from loosening?
This animation shows the simple but effective wedge-locking principle in action. Unlike regular washers that rely on friction, Nord-Lock washers use a unique cam design that locks the bolt securely in place.
When vibration occurs, the washer system creates tension that prevents the bolt from turning loose. In fact, any attempt to loosen the bolt actually increases the clamping force first.
This smart design helps keep machinery safe, reduces maintenance, and prevents costly downtime.
