The Honda 90319-V09-A01 Hexagon Nut (10MM) is a genuine OEM Hexagon Nut designed for HA4118 and HA4120 lawn tractors. As a direct Honda OEM component, this nut is manufactured to the same specification as the original hardware installed at the factory. Honda supersedes fastener part numbers at serial breaks, so confirm your tractor's serial number against the fitment table before ordering to ensure this is the correct listing for your machine.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this Hexagon Nut (10MM) matches the original specification used on HA4118 and HA4120 lawn tractors.
- Exact 10MM Size — the correct thread size is critical for proper clamping; an incorrect nut will not seat properly or maintain the required holding force.
- Serial Number Verification Recommended — Honda updates fastener part numbers at production breaks, so check your serial number against the compatibility table to confirm this is the right nut for your unit.
A hexagon nut is a standard threaded fastener used to secure components together on a bolted joint. On lawn tractors such as the HA4118 and HA4120, fasteners like this nut hold assemblies in place under the vibration and load that come with regular operation. Using the correct size and grade of nut ensures the joint maintains proper clamping force; an undersized or worn nut can work loose over time, compromising the integrity of the assembly it secures.
