A conical spring washer — also known as a Belleville washer — is a dished ring that exerts a controlled spring load when compressed under a fastener. Its cone shape allows it to flex slightly, maintaining consistent clamping tension even as the joint experiences vibration or thermal cycling. When a conical spring washer becomes flattened, corroded, or goes missing, the fastener it supports can work loose over time, leading to movement or noise in the assembly it secures.
