The Honda 90581-310-000 Plain Washer (20MM) is a genuine OEM replacement designed for EB2000, EB2200, EU2000, EU2200, and EU3200 inverter generators. Sourced directly from Honda, this washer matches the original specification used on the production line. Confirm your generator's serial number against the fitment table before ordering, as Honda periodically supersedes hardware across production runs.
Key Features
- Genuine OEM Honda Hardware — supplied by Honda to the exact dimensions specified for these inverter generators, ensuring the correct load distribution and clamping retention at the fastened joint
- 20MM Bore Size — the (20MM) designation identifies this specific variant; verify it matches the washer called out in your generator's parts diagram before ordering
- Broad Inverter Generator Coverage — listed for the EB2000, EB2200, EU2000, EU2200, and EU3200 inverter generators, including the widely used EU2200 portable line
- Serial Number Verification Recommended — Honda updates hardware specifications at production serial breaks, so cross-check your unit's serial number against the compatibility table to confirm this is the correct part
A plain washer distributes the clamping load of a fastener across a wider surface area, preventing the bolt head or nut from pulling through or damaging the mating component. In inverter generators like the EU and EB series, washers like this one appear throughout the assembly wherever consistent clamping pressure and surface protection are required. Using the correct OEM-specified washer ensures the fastener assembly performs as Honda engineered it.
