Nord-Lock Metric 316/A4 Stainless Wedge Locking Washer
Nord-Lock wedge lock washers are a high-quality brand name washer that secure bolted joints with tension instead of friction. A single "washer" is comprised of a pair of lock washers that have cams on one side and radial teeth on the opposite side.
The rise of the cams between the Nord-Lock washers is greater than the pitch of the bolt. When the bolt and/or nut is tightened, the teeth grip and seat against the mating surfaces. The Nord-Lock wedge lock washer is locked in place, allowing movement only across the face of the cams. Any attempt from the bolt/nut to rotate loose is blocked by the wedge effect of the cams.
