Nord-Lock washers prevent bolted connections from loosening – even under the most severe vibration and dynamic loads. It is impossible for our products to loosen unintentionally due to the wedge created underneath the bolt head and nut.

How it works
Nord-Lock bolt securing solutions consist of a pair of washers, installed cam-face to cam-face with radial serrations on the outer sides gripping the mating surface. They use cam-geometry to effectively prevent the bolt from vibrating loose.
Nord-Lock wedge-locking technology secures bolted joints with tension instead of friction. Think of the bolt as a spring that is stretched during tightening as you turn the fastener, creating the required clamp load to hold parts together. Nord-Lock washers secure bolted joints by increasing this clamp load if the bolt tries to rotate loose.
