The Honda 90309-V0B-N00 Flange Nut (8MM) is a genuine OEM replacement designed for HRC216, HRN216, HRX217, HZ54, and HZ60 mowers. As a direct Honda OEM part, this flange nut is manufactured to the same specification as the hardware originally installed at the factory, ensuring correct thread engagement and clamping load. Confirm your mower model and 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 8MM flange nut matches the original specification for thread pitch and flange diameter, delivering the clamping retention the assembly requires.
- Broad Mower Fitment — listed for HRC216, HRN216, and HRX217 gas walk-behind mowers as well as HZ54 and HZ60 battery-powered zero-turn mowers; check your serial number against the fitment table to confirm the correct row for your unit.
- Drop-In Replacement — the integrated flange distributes clamping load across a wider bearing surface than a standard nut, eliminating the need for a separate washer and simplifying reassembly.
A flange nut is a standard hex nut with a wide, washer-like collar built into one face. That integrated flange spreads clamping force over a broader contact area, which helps keep fastened components seated securely under the vibration loads that mowing equipment routinely generates. When a flange nut is worn, cross-threaded, or lost during service, replacing it with the correct OEM part — matched by part number 90309-V0B-N00 — restores the proper clamp load and keeps the assembly torqued to spec.
