A safe bolt locking system that does not rely on traditional techniques
NORD-LOCK offers a safe bolt locking system that does not rely on traditional techniques to secure the fastener. This system uses tension instead of friction to secure bolted joints. The proven wedge locking method, meeting DIN 25201, is superior to any traditional method.
The NORD-LOCK system in-corporates a pair of washers that have cam faces on one side with a cam angle 'a' greater than the thread angle 'ß'. In addition, there are radical teeth on the opposite side. The pre-assembled washers are installed in pairs, cam face to cam face.
