Nord-Lock’s DNV-Compliant Wedge-Locking Method

Nord-Lock's proven wedge-locking method meeting DIN 25201 utilises tension instead of friction to secure a bolted joint, making it superior to traditional methods.

The Nord-Lock bolt securing system incorporates a pair of washers that have cam faces on one side, with the cam angle α greater than the thread pitch β. In addition, there are radial teeth on the opposite sides. The pre-assembled washers are installed in pairs, cam face to cam face.

Nord-Lock's revolutionary wedge-locking method is approved by DNV for preloaded bolted assemblies subjected to dynamic, fatigue, impact and vibration-induced loading. Please download this free white paper to find out more.
