The Honda 90081-KK0-000 Flange Bolt (10X81) is a genuine OEM Flange Bolt designed for GX620 and GX670 horizontal shaft engines. As a factory-sourced fastener, this bolt is produced to Honda's own specifications, ensuring the correct thread pitch, shank length, and integrated flange geometry for the application. Sourcing the correct OEM fastener matters on high-displacement commercial engines like the GX620 and GX670, where proper clamping load is essential to keeping critical assemblies secure under sustained operation.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this flange bolt matches the exact thread specification and dimensions of the original fastener it replaces.
- Integrated Flange Design — the built-in flange distributes clamping load across a wider bearing surface, functioning as bolt and washer in a single piece.
- Direct OEM Replacement — listed for GX620 and GX670 horizontal shaft engines; verify your engine's serial number against the fitment table before ordering, as Honda supersedes fasteners at production breaks.
A flange bolt combines a standard hex bolt with an integrated flanged base that spreads the clamping force over a broader area than a plain bolt alone. On large horizontal shaft engines such as the GX620 and GX670, this even load distribution helps prevent fastener loosening caused by vibration during extended run cycles. When a fastener of the wrong length, thread pitch, or flange diameter is used in its place, joint integrity can be compromised, leading to component movement or damage at the mounting point.
