A spring washer is a hardened, split or wave-form ring placed under a fastener to maintain clamping load as the joint experiences vibration, thermal cycling, or minor settling. When a spring washer is missing, worn flat, or broken, the fastener it seats against is free to back out gradually, which can allow covers, brackets, and assemblies to loosen during operation. Replacing a fatigued spring washer with the correct OEM piece restores the designed clamping retention and keeps the fastener secure through normal service cycles.
