Metric Spring Lock Washers

The arched shape of these washers presses up against a bolt and down against a nut to prevent loosening from wear, vibration, or temperature changes.

Wedge Lock Washers

Comparable to NORD-LOCK® or Sherex TEC Series washers, these two-piece washers provide more locking power than split, tooth, and spring lock washers. Wedges on the inside lock the two pieces together, and serrations on the exterior grip surfaces to resist loosening from high vibration and shifting.

Tab Lock Washers
