A washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it secures. By spreading clamping force across a wider area, it prevents the fastener from digging into or pulling through softer materials and helps maintain consistent tension in an assembly. When a washer wears, deforms, or goes missing, fasteners can loosen under vibration, leading to misalignment or damage to surrounding components — making it a small part with an outsized role in keeping an assembly tight and secure.
