A support washer serves as a precision spacer and load-distributing interface between fastened components within an assembly. It spreads clamping force evenly across mating surfaces, protecting softer materials from deformation and keeping fasteners torqued correctly under operational vibration and stress. When a support washer is worn, deformed, or missing, adjacent components can shift or sustain accelerated wear, compromising the integrity of the entire assembly — making replacement with a correctly specified part essential for the DM406 and WS460-series machines.
