Tooth Washers - External-Internal Combination - Steel, Zinc Plated

A locking washer with teeth or prongs which extend outward from the outside edge of the washer as well as on the inside edge. This maintains essential tension and opposes any loosening influence on the fastener. The flexed teeth absorb shock, vibration and slipping.

The combination tooth washer is preferred when a larger bearing surface is required. It is also often used when there is an oversized hole.
