Lock Washers, Metric, Zinc Plated

Also known as a split washer, a lock washer is a special type of washer that’s designed to create tension so that the bolt doesn’t loosen or otherwise come out of its installed position. Lock washers aren’t flat. They feature a semi-coiled design that gradually rises. This design allows lock washers to create tension when installed. Lock washers work by preventing the rotational movement of the installed bolt.
