The Honda 90320-V09-A01 Self-Lock Nut (6MM) is a genuine OEM fastener designed for the HA4118 and HA4120 lawn tractors. As a direct Honda OEM component, this nut is manufactured to the exact specification Honda engineers selected for these machines, ensuring a correct, secure fit every time. Confirm your tractor's serial number against the fitment table before ordering, as Honda updates part numbers at production breaks. This genuine OEM part is the straightforward, by-the-book replacement when the original needs to be swapped out.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, so the thread pitch, locking collar geometry, and dimensional tolerances match what came off the assembly line on HA4118 and HA4120 lawn tractors
- Self-Locking Design — the integral locking feature resists loosening under vibration, maintaining clamp load through the normal operating cycles of the tractor
- Verified Fitment — listed under Honda part number 90320-V09-A01 for the HA4118 and HA4120 lawn tractors; check your serial number against the fitment table to confirm the correct application
A self-lock nut uses a deformed or nylon-insert locking element that grips the bolt threads and resists rotation caused by vibration or cyclical loading. On a lawn tractor, fasteners are exposed to constant engine vibration and ground shock, and a nut that backs off can allow components to shift or separate. Replacing a worn or missing self-lock nut with the correct OEM unit restores the holding force the original assembly depended on.
