The Honda 90106-YE5-641 Hexagon Bolt (8X20) is a genuine OEM Hexagon Bolt (8X20) designed for WP20 and WP30 water pumps. Sourced directly from Honda, this bolt matches the exact dimensions and thread specification Honda engineered into these pumps at the factory. It is listed for both the WP20 and WP30 — confirm part number 90106-YE5-641 against your pump's serial number and parts diagram before ordering to ensure this is the correct fastener for your specific unit.
Key Features
- Genuine OEM Honda Fastener — supplied by Honda to the exact size and thread specification required, so the bolt seats and torques correctly without chasing threads or shimming gaps.
- Correct 8 x 20 mm Specification — the (8X20) designation identifies the thread diameter and shank length; match this to your parts diagram to confirm it is the right fastener for your application.
- WP20 and WP30 Water Pump Fitment — listed for Honda WP20 and WP30 centrifugal water pumps; check your serial number against the fitment table to verify applicability to your unit.
A hexagon bolt is a standard threaded fastener used throughout Honda water pump assemblies to secure covers, housings, and structural components. Using the correct OEM bolt — right thread pitch, right shank length — ensures proper clamp load and keeps the assembly held to Honda's designed tolerances. An incorrect fastener can strip threads, allow components to loosen under vibration, or prevent proper sealing where a gasket or mating surface is involved.
