The Nord-Lock anti-vibration washer fixes the bolted connection by means of tension, not friction. The system consists of two washers having wedges on one side and radially arranged teeth on the other side. The stop-wedge effect occurs because the wedge angle "α" is greater than the pitch of the thread "β". This reliably ensures the prevention of self-unscrewing of the threaded connection.
