The Honda 90038-ME9-000 Special Bolt (10MM) is a genuine OEM fastener designed for GX640 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the exact specification Honda engineers called for, ensuring a proper fit without guesswork or modification. This Special Bolt (10MM) is the correct replacement when the original hardware is damaged, stripped, or lost during service.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this bolt matches the exact thread pitch, diameter, and head geometry specified for the GX640 engine, so it installs and torques correctly the first time.
- Correct Variant for GX640 Engines — listed specifically for GX640 horizontal shaft engines; confirm your serial number against the fitment table to ensure this is the right hardware for your production range.
- Purpose-Built Fastener — Honda designates this as a "special" bolt rather than a standard metric fastener, meaning it carries a unique specification; substituting a generic 10MM bolt risks improper clamping or fitment.
A special bolt differs from a standard metric fastener in at least one critical dimension — thread form, shank length, head style, or shoulder geometry — which is why Honda catalogs it separately rather than pointing to a common hardware substitute. Using the correct part number 90038-ME9-000 ensures the fastener seats and clamps as intended within the GX640 engine assembly. Installing an incorrect or generic substitute can lead to improper torque retention, fastener failure, or damage to the component it secures.
