The Honda 90107-VA5-640 Flange Bolt (6X10) is a genuine OEM fastener designed for a wide range of Honda equipment, including GX640 horizontal shaft engines, the EX350 inverter generator, H4518 and H5518 tractors, and HR194, HR195, HR214, HR215, and HR216 lawn mowers. As a direct Honda OEM part, this flange bolt is manufactured to the same specifications as the original hardware it replaces. Always verify your machine's serial number against the fitment table — Honda updates parts at serial breaks, and confirming your serial range ensures you receive the correct bolt for your unit.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this flange bolt matches the original specification for thread pitch, head dimensions, and clamping load required by each application.
- Broad Fitment — listed for GX640 horizontal shaft engines, the EX350 inverter generator, H4518 and H5518 tractors, and HR-series walk-behind lawn mowers, including the HR194, HR195, HR214, HR215, and HR216.
- Verify Your Serial Number — Honda supersedes fasteners at production serial breaks; check your machine's serial number against the fitment table before ordering to confirm this is the correct part for your unit.
- Integrated Flange Design — the built-in flange distributes clamping force evenly across the mating surface, eliminating the need for a separate flat washer and maintaining consistent joint integrity.
A flange bolt combines a standard hex bolt with a wide, integrated flange beneath the head that acts as a built-in washer. This flange spreads the clamping load over a larger surface area, helping to keep fastened components seated securely even under vibration — a common condition across engines, mowers, and tractors in regular service. When a flange bolt stretches, corrodes, or is lost, the joint it secures can loosen progressively, leading to misalignment or component separation that may require more extensive repairs to correct.
