The Nord-Lock bolt securing system incorporates a pair of washers that have cam faces on one side and radial teeth on the opposite side. The pre-assembled washers are installed in pairs, cam face to cam face.
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.
When the bolt and/or nut is tightened the teeth of the Nord Lock washers grip and lock the mating surfaces, allowing movement only across the cam faces. Any rotation of the bolt/nut is blocked by the wedge effect of the cams.
