The Honda 90109-ZG5-003 Screw Washer (4X24) is a genuine OEM component designed for the EB12 generator. As a direct Honda OEM part, it is made to the exact specifications Honda requires for the EB12, ensuring a proper fit without guesswork. Always confirm your unit's serial number against the fitment table before ordering, as Honda periodically supersedes parts at production breaks.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this screw washer matches the original part in thread size and washer geometry, delivering the correct clamp load for its application on the EB12 generator.
- Exact Fit for EB12 Generators — engineered specifically for the EB12 generator, this part installs directly without modification, maintaining the integrity of the assembly it secures.
- Check Your Serial Number — Honda revises part fitment at serial number breaks, so verify your generator's serial number against the compatibility table to confirm part number 90109-ZG5-003 is correct for your unit.
A screw washer combines a threaded fastener and an integrated washer into a single piece, distributing clamping load evenly across the surface being secured and reducing the risk of loosening under vibration. In a generator like the EB12, where sustained engine operation produces continuous vibration, using the correct OEM fastener ensures panels, covers, and components stay properly secured. A missing or incorrect screw washer can lead to loose assemblies and accelerated wear at the fastening point.
