Adhesive Lock Washers
When a metal fastener is tightened onto the washer, the embedded epoxy activates and bonds the underside of the fastener head to the mating surface to prevent loosening. The adhesive fills gaps and spaces that other washers fail to seal. Made from fiberglass, these washers have excellent resistance to salt water.
