External Tooth Washers


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

Applications:
The external tooth washer is preferred when finished appearance is less crucial as it provides the greatest torsional resistance and therefore locking efficiency because the teeth are on the largest radius.
