The Honda 90103-Z08-E30 Screw Washer (6X12) is a genuine OEM fastener designed for Honda EB10000, EB11000, and ES6500 generators. As a direct Honda OEM part, it is manufactured to the same specifications as the original hardware installed at the factory, ensuring a correct fit without guesswork. Confirm your generator's serial number against the fitment table before ordering, as Honda periodically updates part numbers at serial breaks.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this screw washer matches the original fastener specification for the EB10000, EB11000, and ES6500 generators
- Integrated Washer Design — the combined screw-and-washer construction distributes clamping load evenly, keeping the mating surface secure without a separate loose washer
- Check Your Serial Number — Honda updates hardware at production breaks, so verify your generator's serial number against the compatibility table to confirm this is the correct revision for your unit
A screw washer is a fastener that combines a screw and a captive washer in a single piece, distributing clamping force across a broader surface area than a plain screw alone. On Honda generators such as the EB10000, EB11000, and ES6500, these fasteners are used throughout the assembly to hold covers, panels, and components securely in place during operation. Using the correct OEM replacement ensures the thread engagement and bearing surface match the original design — a mismatched fastener can work loose under vibration or damage the mating material over time.
