The Honda 90011-888-000 Flange Bolt (8X90) is a genuine OEM replacement designed for the GV150 vertical shaft engine. As a direct Honda OEM part, it is manufactured to the exact dimensions specified for this engine, ensuring the correct thread pitch, shank length, and flange diameter are present for a proper fit. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes hardware at production breaks.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this flange bolt meets the exact dimensional specifications called out for the GV150 engine, so there is no guesswork on thread pitch or shank length
- Integrated Flange Design — the built-in flange distributes clamping load evenly across the mating surface, eliminating the need for a separate washer and maintaining consistent holding force
- Serial Number Verification Recommended — Honda updates hardware specifications at production breaks, so cross-check your GV150 serial number against the fitment table to confirm part number 90011-888-000 is correct for your unit
A flange bolt combines a standard hex bolt with an integral flanged bearing surface beneath the head. That flange acts like a built-in washer, spreading the clamping load over a wider area to resist loosening under vibration — a common condition in small engine applications. When a flange bolt is worn, stripped, or replaced with an incorrect fastener, the joint it secures can lose clamping force, leading to component movement or leaks at the mating surface.
