The Honda 90112-187-010 Flange Bolt (5X25) is a genuine OEM fastener designed for F220 tillers and GX640 horizontal shaft engines. As a factory-sourced component, this bolt is manufactured to the same specifications as the original hardware, ensuring a correct fit right out of the box. Confirm your machine's serial number against the fitment table below before ordering, as Honda supersedes hardware at serial breaks.
Key Features
- Genuine OEM Honda Hardware — sourced directly from Honda, this flange bolt matches the original fastener in thread pitch, shank length, and flange diameter, so it seats the way the factory intended.
- Integrated Flange Design — the built-in flange distributes clamping load across a wider bearing surface, reducing the risk of loosening under vibration without requiring a separate washer.
- Confirmed Fitment — listed for F220 tillers and GX640 horizontal shaft engines; always verify part number 90112-187-010 against your machine's serial number using the compatibility table.
A flange bolt combines a standard hex bolt with a wide, integrated flange beneath the head that acts like a built-in washer. This wider bearing surface spreads clamping force over a larger area, helping the fastener hold securely even when the engine or equipment is running under load and generating vibration. When a flange bolt loosens or is replaced with an incorrect fastener, clamping force is compromised, which can allow mated components to shift or work loose over time.
