The Honda 90101-YE5-003 Bolt-Washer (8X20) is a genuine OEM fastener designed for WP20 and WP30 water pumps. As a direct Honda OEM component, it is manufactured to the same standards as the original hardware installed at the factory, ensuring a correct fit without modification. This part is listed for both the WP20 and WP30 — confirm your pump model and serial number against the fitment table before ordering. Honda supersedes hardware at production breaks, so verifying your serial number is the most reliable way to confirm this is the right fastener for your unit.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this bolt-washer combination meets the original torque and clamping specifications for WP20 and WP30 water pumps
- Integrated Washer Design — the combined bolt and washer construction distributes clamping load evenly, eliminating the need to source and align a separate washer during reassembly
- Serial Number Verification Recommended — Honda updates fastener specifications at production breaks; check your pump's serial number against the fitment table to confirm this is the correct part for your unit
A bolt-washer is a fastener that combines a bolt and a captive washer into a single piece. In a water pump like the WP20 and WP30, these fasteners are used to secure components under sustained vibration and load from the pump's operation. Using the correct OEM fastener matters because an incorrect thread pitch, shank length, or washer diameter can result in inadequate clamping, loosening under vibration, or damage to the mating surface over time.
