The Honda 90091-ZS3-003 Bolt-Washer (5X135) is a genuine OEM fastener designed for EZ3500 and EZ5000 generators. As a direct Honda OEM component, this bolt-washer is sourced from the same supply chain as the original hardware installed at the factory. Confirm your generator's serial number against the fitment table before ordering, as Honda periodically supersedes hardware at production breaks.
Key Features
- Genuine OEM Honda Hardware — sourced directly from Honda, this bolt-washer matches the original specification for EZ3500 and EZ5000 generators, ensuring the correct thread pitch, length, and integrated washer bearing surface.
- Exact-Match Fastener — the 5X135 designation identifies this as a specific size variant; confirm this matches the mounting point on your unit before installing.
- Serial Number Verification Recommended — Honda updates hardware specifications across production runs, so cross-check your generator's serial number against the fitment table to confirm this is the correct bolt-washer for your machine.
A bolt-washer is a fastener that combines a bolt and an integrated washer into a single component, distributing clamping load evenly across the surface it bears against. This prevents the fastener from pulling through or deforming the material it secures, maintaining consistent clamping force over time. Using the correct OEM bolt-washer ensures the proper torque is retained and that the assembly stays securely fastened through the vibration cycles a generator produces during operation.
