Key Features
- Genuine Honda OEM — factory-original hardware that matches the specification Honda engineers built the WT20 and WT30 water pumps around, so thread pitch, shank diameter, and washer dimensions are exactly right.
- Integrated Washer Design — the captive washer distributes clamping load evenly, reducing the chance of loosening under the vibration a working pump generates.
- Check Your Serial Number — Honda updates hardware specifications at production breaks, so verify your pump's serial number against the compatibility table before finalizing your order.
A bolt-washer is a one-piece fastener that combines a hex bolt with a permanently attached washer flange. On Honda WT20 and WT30 water pumps, these fasteners are used where consistent clamping force across a broader surface area is needed. When a bolt-washer becomes stripped, corroded, or damaged, it can allow assembled components to work loose during operation, which can lead to leaks, vibration issues, or further damage to the pump. Replacing a worn fastener with the correct OEM part restores the proper clamp load and keeps the pump running as intended.
