Honda 90516-Z25-000 Plain Washer (10.3X34)

The Honda 90516-Z25-000 Plain Washer (10.3X34) is a genuine OEM component designed for the EU6500 inverter generator. Sourced directly from Honda, this washer carries the exact dimensions Honda specified for this application — 10.3 mm inner diameter by 34 mm outer diameter — so it seats correctly without shimming or substitution. Keeping the correct hardware in place ensures fastener load is distributed as Honda intended across the mating surfaces on your EU6500.

Key Features

• Genuine OEM Specification — manufactured to Honda's exact dimensional requirements, ensuring the washer seats flush and carries the correct load for its application on the EU6500
• Exact-Fit Dimensions — the 10.3 mm bore and 34 mm outer diameter are specific to this Honda part number 90516-Z25-000; using an incorrect-size washer risks uneven clamping or fastener movement
• Confirm Your Serial Number — Honda updates hardware specifications at production breaks, so verify your EU6500 serial number against the fitment table before ordering to ensure this is the correct washer for your unit

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 distorting the mating material. On the EU6500 inverter generator, correctly sized washers keep fastener assemblies secure through the vibration and thermal cycling that accompany regular operation. When a washer of the wrong size or thickness is used, clamping force concentrates unevenly, which can lead to loosening or surface damage over time.
