Honda 90551-Z44-000 Plain Washer (10mm)

The Honda 90551-Z44-000 Plain Washer (10mm) is a genuine OEM component designed for EB2200 and EU2200 inverter generators. As a direct Honda OEM part, it is manufactured to the exact dimensions Honda specifies for these generators, ensuring proper fit without rework or adjustment. Confirm your generator's serial number against the fitment table before ordering, as Honda updates parts at specific production breaks and part number 90551-Z44-000 may not apply to every serial range within these models.

Key Features

• Genuine Honda OEM — sourced directly from Honda's parts catalog, so dimensions and material are exactly what the EB2200.
• Correct 10mm Sizing — the (10mm) designation identifies this specific variant; verify the size against your generator's parts diagram before purchasing
• Fits EB2200 and EU2200 Inverter Generators — listed for both models; check your serial number against the fitment table to confirm this washer applies to your unit
• Serial Number Awareness — Honda supersedes hardware at production breaks, so matching your serial number to the fitment data is the most reliable way to confirm the right part

A plain washer distributes the clamping load of a fastener across a broader surface area, protecting the material being fastened and helping the assembly hold its torque over time. In an inverter generator like the EB2200 and EU2200, washers are used throughout the frame, panel, and internal assembly to keep hardware secure under the vibration of normal operation. When the correct washer is missing or the wrong size is used, fasteners can work loose, surfaces can deform, and hardware can fail to seat properly — all of which can lead to rattles, misalignment, or fastener loss during use.
