Lockwasher External Tooth
Lockwasher External Tooth: A hardened circular washer with twisted prongs or "teeth" which extend out from the outer edge of the washer. This is the most preferable of all tooth-lock washers. It offers the greatest locking efficiency since the teeth are on the largest radius and provide greater torsional resistance. *ZB - BLUE ZINC
