Nord-Lock Wedge Locking Washers - Stainless Steel (254 SMO) Washer, Vibration Resistant Safety Washers for M4 Bolts - 10 Pairs

The Nord-Lock system is comprised of a pair of washers that has cams on one side and radial teeth on the opposite side. Since the cam angle is greater than the thread pitch, a wedge effect is created by the cams, preventing the bolt from rotating loose. Over the operational life cycle, Nord-Lock washers offer increased operational reliability and lower maintenance costs, while significantly reducing the risks of production stops, accidents and warranty claims. The Nord-Lock Group is a world leader in secure bolted solutions. Our mission is to safeguard human lives and customer investments. Our products are recognized for their ability to safely secure bolted joints exposed to severe vibration and dynamic loads.
