The Honda 90316-V09-A01 Flange Nut (8MM) is a genuine OEM component designed for HA4118 and HA4120 lawn tractors. As a direct Honda OEM part, this nut is manufactured to the exact dimensions and thread specification Honda requires for these tractors. Verify your tractor's serial number against the fitment table before ordering to confirm this is the correct listing for your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, ensuring the correct 8MM flange thread specification for the HA4118 and HA4120 lawn tractors
- Integrated Flange Design — the built-in flange distributes clamping load evenly, eliminating the need for a separate flat washer and maintaining consistent holding force
- Exact Replacement — matches part number 90316-V09-A01 precisely; confirm your serial number against the fitment table to ensure this is the right nut for your application
A flange nut combines a standard hex nut with an integral wide-bearing flange at its base. The flange spreads clamping force across a larger contact area than a plain nut, preventing fastener pull-through and keeping assemblies securely torqued under vibration. On lawn tractors like the HA4118 and HA4120, loose or damaged hardware can allow components to shift or separate during operation, so replacing worn or missing fasteners with the correct OEM specification nut is a straightforward but important part of routine maintenance.
