The Honda 90301-V09-A01 Flange Nut (8MM) is a genuine OEM replacement designed for HA4118 and HA4120 lawn tractors. As a direct Honda OEM part, it is manufactured to the same specification as the original hardware fitted at the factory. Buyers should confirm compatibility by checking their tractor's serial number against the fitment table before ordering, as Honda supersedes hardware across production runs.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this flange nut meets the original torque and clamping specification for the HA4118 and HA4120.
- Exact OEM Replacement — matches the thread pitch, flange diameter, and 8MM sizing of the original nut for a direct, drop-in swap.
- Verify by Serial Number — Honda updates hardware specifications at serial breaks; always cross-reference your tractor's serial number with the fitment table to confirm this is the correct nut for your unit.
A flange nut combines a standard nut with an integrated wide-bearing flange that distributes clamping load across a broader surface area than a plain nut. This helps prevent the fastener from pulling through or distorting the mating material, maintaining a secure, vibration-resistant connection over the service life of the machine. A worn, stripped, or missing flange nut can result in loosening under the vibration of normal tractor operation, making timely replacement with the correct OEM part important.
