The Honda 90014-888-000 Flange Bolt (6X50) is a genuine OEM fastener designed for a wide range of Honda vertical shaft engines, horizontal shaft engines, lawn mowers, and lawn tractors, including the GCV160, GCV190, GXV160, HRX217, HR216, and H4013, among others. As an authentic Honda part, this bolt is manufactured to the exact dimensions Honda specifies, ensuring proper clamping load and thread engagement wherever it is used in these assemblies. Check your machine's serial number against the fitment table to confirm this is the correct bolt for your specific unit — Honda supersedes hardware at production breaks, and getting the right part number matters.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this bolt meets the exact dimensional and mechanical specifications Honda engineering calls for, not an approximation.
- Integrated Flange Design — the built-in flange distributes clamping load across a wider bearing surface, reducing the risk of fastener loosening under vibration without needing a separate washer.
- Broad Fitment — listed for GCV160, GCV170, GCV190, GCV200, GSV190, GV150, GV200, GV400, GX640, GXV160, H4013, H5518, HR21, HR216, HRA21, HRA216, HRC216, HRN216, HRR216, HRS216, and HRX217; confirm your serial number against the fitment table before ordering.
- Exact Thread and Length Specification — the 6 x 50 mm sizing is a specific Honda callout; substituting a generic fastener of the same nominal size risks incorrect torque retention and thread fit in the original tapped bore.
A flange bolt combines the function of a standard hex bolt with an integral load-spreading flange at the base of the head. In Honda engines, mowers, and tractors, fasteners like this one are used throughout the assembly to secure components under sustained vibration — the flange bears against the mating surface and helps maintain clamp force without a separate hardened washer. When the correct bolt is missing or replaced with an incorrect substitute, thread engagement and clamping load can fall short of Honda's specification, which may allow joints to work loose during operation. Using the correct OEM part, matched by part number 90014-888-000, ensures the joint behaves exactly as Honda designed it.
