A lock washer is a fastening component placed beneath a nut or bolt head to resist loosening caused by vibration, torque, or cyclical loading. The washer's spring tension or serrated edges bite into the mating surface and the fastener, maintaining clamping force over time. A worn, deformed, or missing lock washer allows fasteners to back out gradually, which can lead to loose joints and the need for more frequent re-torquing. Replacing a damaged washer with the correct OEM part restores the joint to its intended clamping specification.
