The Honda 90303-V09-A01 Special Nut (8MM) is a genuine OEM Special Nut (8MM) designed for HA4118 and HA4120 lawn tractors. As a direct Honda OEM component, this nut is manufactured to the exact specification Honda requires, ensuring proper torque retention and a correct mechanical fit. Honda supersedes parts at serial number breaks, so confirm your tractor's serial number against the fitment table before ordering to make sure part number 90303-V09-A01 is the right match for your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this Special Nut (8MM) meets the exact specification called out in Honda's own parts catalog for the HA4118 and HA4120.
- Correct 8MM Sizing — the 8MM designation is part of the part's identity; confirm this matches the fastener position on your tractor before installing.
- Lawn Tractor Fitment — listed for the HA4118 and HA4120 Honda lawn tractors; check your serial number against the compatibility table to confirm applicability to your machine.
- Secure Mechanical Connection — a properly seated special nut maintains the clamping load Honda engineered into the joint; a damaged or missing nut can allow components to loosen under the vibration and load a lawn tractor generates during operation.
A special nut differs from a standard hex nut in that Honda has engineered a specific geometry, thread form, or retention feature into it to suit a particular joint on these lawn tractors. This means an ordinary hardware-store nut of the same nominal size is unlikely to perform the same way. Using the correct Honda OEM nut ensures the joint holds at the clamping load and torque value the tractor was designed around, keeping connected components properly secured through normal mowing operation.
