The Honda 90091-ZR8-T62 Bolt-Washer (5X210) is a genuine OEM fastener designed for Honda EB and EM series generators. As a direct OEM replacement, this bolt-washer is manufactured to Honda's original specifications, ensuring consistent fit across the generator models it is listed for. Confirm your generator's serial number against the fitment table before ordering, as Honda periodically supersedes fasteners at production breaks.
Key Features
- Genuine Honda OEM Fastener — sourced directly from Honda, this bolt-washer matches the original hardware exactly, eliminating guesswork on thread pitch and shank length.
- Broad Generator Fitment — listed for Honda EB3800, EB4000, EB5000, EB6500, EM3800, EM4000, EM5000, and EM6500 generators; verify your serial number against the fitment table to confirm the correct application.
- Integrated Washer Design — the captive washer distributes clamping load evenly, maintaining consistent retention without requiring a separate washer during reassembly.
A bolt-washer is a fastener that combines a threaded bolt shank with an integrated washer flange. The washer flange spreads the clamping force over a wider surface area than a plain bolt head alone, helping to secure components firmly and resist loosening under the vibration loads that generators produce during operation. When this fastener is missing, damaged, or replaced with a non-matching substitute, the clamping force becomes uneven and the secured component may shift or work loose over time. Using the correct OEM part number 90091-ZR8-T62 ensures the thread engagement and washer geometry match what Honda engineered for these generators.
