The Honda 94103-05800 Plain Washer (5MM) is a genuine OEM component used across a wide range of Honda equipment, including GCV160 vertical shaft engines, GX640 horizontal shaft engines, EU1000, EU3200, and EX700 inverter generators, EL5000, ES6500, and EX5500 generators, BF2 and BF20 portable outboard motors, HRR216 and HRS216 lawn mowers, F200 tillers, and H2013 and H2113 lawn tractors, among others. As a Honda OEM part, it is manufactured to the same specification as the original hardware used on the production line. Because this washer appears across many Honda product lines and serial ranges, always confirm part number 94103-05800 against your equipment's model and serial number before ordering. A correctly fitted washer ensures proper clamping load at the fastener joint it serves.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda's parts catalog, matching the original washer specification for every model this part is listed under.
- 5MM Bore Size — sized for 5MM fasteners; verify this matches your application before ordering, as Honda lists multiple washer sizes across its equipment range.
- Broad Cross-Line Fitment — listed for Honda engines, inverter generators, conventional generators, a welder generator, outboard motors, lawn mowers, lawn tractors, a tiller, and a robotic mower, including GCV160, GX640, EU3200, BF20, HRR216, and more.
- Check Your Serial Number — Honda supersedes hardware at production breaks; confirm your unit's serial number against the fitment table to ensure this is the correct washer for your machine.
A plain washer distributes the clamping load of a fastener across a broader surface area, protecting the mating components from damage and preventing the fastener from pulling through or deforming the material it secures. In Honda equipment, plain washers appear at dozens of assembly points spanning engines, drivetrain covers, generator frames, mower decks, and marine components. When a washer is missing, undersized, or deformed, the fastener joint loses clamping integrity, which can lead to loosening under vibration and accelerated wear of the surrounding components. Using the correct OEM replacement ensures the joint performs as Honda designed it.
