The Honda 90402-ZG5-003 Plain Washer (10MM) is a genuine OEM component designed for the EB12 generator. As a direct Honda OEM part, it carries the correct dimensions to seat and retain fasteners exactly as the original design requires. Confirm your unit's serial number against the fitment table to ensure this is the right washer for your machine before ordering.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this washer meets the same dimensional spec as the original hardware it replaces.
- Correct 10MM Sizing — the 10MM bore matches the fastener it is built around, ensuring proper load distribution and a flush seat.
- EB12 Generator Fitment — listed for the Honda EB12 generator; verify your serial number against the fitment table to confirm applicability.
A plain washer distributes the clamping load of a bolt or nut across a wider surface area, protecting the surrounding material from being damaged or deformed under torque. In a generator like the EB12, plain washers appear at multiple fastener points throughout the assembly, keeping hardware seated securely during operation. When a washer is missing, undersized, or worn, the fastener can work loose over time or pull through the material it bears against, leading to vibration issues or damaged housings.
