A washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it bears against. By spreading clamping force over a wider area, it prevents the fastener from pulling through or damaging softer materials, and helps maintain consistent tension in assemblies subject to vibration. In pump applications like the Wacker Neuson PT series, where engines and impellers generate continuous vibration during operation, a worn, deformed, or missing washer can lead to fastener loosening, joint failure, and damage to adjacent components. Replacing a worn washer promptly keeps assemblies secure and protects the integrity of the surrounding hardware.
