The Honda 94101-03800 Plain Washer (3mm) is a genuine OEM replacement designed for a wide range of Honda equipment, including E2500, EG650, EL5000, EM500, EM600, and EX800 generators, the FG110 tiller, HR214 lawn mower, and HRM3000, HRM310, and HRM520 robotic mowers. Sourced directly from Honda, this washer matches the exact dimensions and material specification called out in Honda's parts catalogue for these applications. Always confirm fitment using your unit's model and serial number against the compatibility table, as Honda occasionally revises hardware across production runs.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, matching the exact 3mm specification listed for each compatible model in Honda's parts catalogue.
- Direct-Fit Replacement — sized to Honda's original dimension so this washer drops into position without modification.
- Broad Compatibility — listed for Honda generators, the FG110 tiller, the HR214 lawn mower, and HRM-series robotic mowers; confirm your model and serial number before ordering.
- Correct Load Distribution — a properly sized plain washer spreads clamping load evenly across the fastened surface, preventing fastener pull-through and helping maintain a secure assembly over time.
A plain washer is a flat, circular disc placed under a fastener to distribute the clamping load over a wider surface area, protecting the material being fastened and helping the joint hold its torque. At 3mm, this washer is sized for small-diameter fasteners found throughout Honda's equipment assemblies. When the wrong washer is used — or when one is missing — the fastener can bite into the surrounding surface, leading to loosening, deformation, or damage to the assembly it secures.
