Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, so this bolt-washer matches the thread pitch, shank diameter, and clamping dimensions of the original fastener exactly.
- Integrated Washer Design — the captive washer distributes clamping load evenly, eliminating the need for a separate loose washer and simplifying reassembly.
- WP20 and WP30 Fitment — listed for Honda WP20 and WP30 water pumps; check your unit's serial number against the fitment table to confirm this is the correct part for your pump.
A bolt-washer is a fastener that combines a bolt and a fixed washer in a single piece. The washer distributes the clamping force across a wider surface area, helping to keep components securely seated during operation. On water pumps like the WP20 and WP30, where vibration and fluid pressure place ongoing stress on assembled joints, using the correct OEM fastener ensures the proper torque and seating are maintained. A worn, stripped, or incorrectly sized bolt-washer can allow joints to work loose over time, leading to leaks or component misalignment.
