Keyed, External


DIN 432 Metric External Keyed Washers are a type of tab washer used with hexagon head screws or hexagon nuts to keep them from rotating. Whereas most lock washers rely on friction or a spring load between the fastener and the mating surface to keep a fastener from loosening, Tab Washers are bent against the side of fastener to keep it from turning.

DIN 432 Metric External Keyed Washers are round washers with a large outside diameter and a tab that protrudes down on the outside of the washer. The tab is designed to fit into a hole or a slot that has been cut into the mating surface and then part of the washer is bent up against the head of the fastener.

Metric & Multistandard Components Corp. offers DIN 432 Metric External Keyed Washers in Steel and Stainless Steel. Please contact one of Metric & Multistandard’s customer service representatives at any of our five locations for assistance.
