The system comprises of a pair of washers that has cams on one side and radial teeth on the opposite side. Nord-Lock wedge-locking products positively lock the fastener in a joint which is subjected to extreme vibration or dynamic loads. The key is the difference in angles. Since the cam angle \" α \" is larger than the thread pitch \" β \", the pair of washers expand more than the corresponding pitch of the thread.
