Stainless steel. SP (enlarged outer diameter)
Tension makes the bolt self-locking
Nord-Lock wedge-locking technology secures bolted joints with tension instead of friction. 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.
