Nord-Lock wedge-locking washers are made specifically for use with M8 steel bolts. Each pack contains 20 glued pair of washers. Applications for Nord-Lock Carbon Steel washers include general steel applications. Nord-Lock washers utilize tension instead of friction in order to secure bolted joints exposed to severe vibration and dynamic loads. Nord-Lock steel washers promise the highest corrosion resistance on the market. Nord-Lock multifunctional wedge-locking washers are used in industries such as: energy, robotics, medical, transportation, offshore, mining and quarrying, construction and bridge building, manufacturing and processing, ship building, forestry and agriculture, heavy vehicles, and military.

Nord-Lock washers feature a unique system that 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.
