A plain washer distributes the clamping load of a fastener across a broader surface area, protecting the mating material from damage and helping the fastener maintain consistent holding force over time. In a water pump like the WT40, where vibration and wet operating conditions are routine, using the correct OEM-specified washer ensures fastener assemblies remain secure through normal service cycles. Installing the wrong size can allow fasteners to loosen prematurely or damage the surfaces they bear against.
