The Honda 94101-05800 Plain Washer (5mm) is a genuine OEM component used across an extensive range of Honda generators, engines, tillers, riding mowers, lawn tractors, multi-purpose tractors, compact tractors, lawn mowers, and water pumps, including models E1500, E2500, EB3500, EB3800, EB4000, EB5000. As a genuine Honda part, it is manufactured to the same standards as the original hardware installed at the factory. With fitment spanning such a wide variety of Honda equipment, verifying your machine's model and serial number against the compatibility table before ordering is the best way to confirm this is the correct washer for your application.

- Direct Drop-In Replacement — the 5mm sizing matches the original fastener stack, so installation requires no reworking of the surrounding hardware
A plain washer distributes the clamping load of a fastener — bolt, screw, or nut — across a wider surface area, preventing the fastener head from digging into or deforming the material beneath it. In assembled equipment, plain washers also help maintain consistent clamping force, keeping joints secure under vibration and load cycling. When a washer is worn, distorted, or missing entirely, the fastener can work loose or cause surface damage to the components it is meant to hold, leading to unwanted movement or the need to replace otherwise serviceable parts.
