Product details
This flat washer is stainless steel with a .563 in. inside diameter, listed by Powr-Flite as part 19616.
Putting a flat washer under a bolt head or nut spreads out the clamping force over more surface area, so the joint can be torqued down firmly without the fastener biting into the panel underneath it. Stainless makes sense here because this hardware sees water and cleaning chemical routinely on wet-pickup and extraction machines, and a plated washer in that spot rusts and can eventually seize onto the very fastener it was meant to protect.
- Part: 19616
- Type: plain flat washer
- Inside diameter: .563 in.
- Material: stainless steel
Check that the inside diameter matches your bolt before ordering. A washer too large for its bolt sits crooked instead of centering flat under the head, which defeats the purpose of adding one in the first place. Loose or missing hardware on cleaning equipment is a common source of rattles and shifting panels, and a worn or missing washer is a cheap first thing to check before assuming a larger part has failed. Keep a few spares on hand if you service this equipment regularly, since flat washers this size go missing during teardown more often than any other fastener on the machine.
