The Disc-Lock Washer harnesses Disc-Lock’s wedge-locking system to prevent nuts and bolts coming loose. Under vibration, a nut or bolt will attempt to rotate loose but the interlocking cams and non-slip ridges of the Disc-Lock Washer work together to create a jamming effect, preventing the nut or bolt from rotating and maintaining joint integrity.
