AYA FASTENERS Guide | What Are Spring Steel Washers?
Dec 19, 2023
Spring Steel Washer
Spring washers, commonly called split lock washers, possess the ability to withstand vibrations due to their unique design. These washers feature a split ring that is bent into a helical shape at one point. This forces the washer to apply spring force between the bearing face and the fastener's head, keeping the washer firmly against the face and the bolt thread firmly against the nut or threaded hole, increasing friction and resistance to rotation.
