Locking and Sealing Washers - LSW-M20-1

Product Description

This washer's unique geometry creates an interference both on the OD of a hex nut and on the ID on the shanks or the thread of the screw. As the screw is tightened the OD cold flows around the hex of a nut and the ID cold flows into the threads of the bolt or screw.
