The Honda 90004-ZM7-V30 Flange Bolt (5X80) is a genuine OEM fastener designed for the GXH50 horizontal shaft engine. As a direct Honda replacement, this bolt matches the original specification and installs without modification. Confirm your engine's serial number against the fitment table before ordering to ensure this is the correct part for your unit.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this flange bolt carries the same part number 90004-ZM7-V30 as the original, ensuring it meets Honda's own standard for the GXH50.
- Integrated Flange Design — the built-in flange distributes clamping load evenly across the mating surface, reducing the need for a separate washer and maintaining consistent holding force.
- GXH50 Fitment — listed for GXH50 horizontal shaft engines; verify your serial number against the compatibility table to confirm this is the correct fastener for your engine.
A flange bolt combines a standard bolt with a wide, integrated flange at the base of the head that acts like a built-in washer. In an engine application, this design spreads clamping load over a broader surface area, helping components seat securely without concentrating stress at a single point. Using the correct OEM bolt ensures the thread pitch, shank length, and flange diameter all match the original, which matters whenever consistent torque retention is needed over extended service hours.
