The Honda 90303-752-000 Hexagon Nut (10MM) is a genuine OEM fastener designed for Honda H-series riding mowers and tractors, including the H3011, H3013, H4013, H4514, H4518, H5013, H5518, and RT5000. As a direct Honda OEM component, this nut is manufactured to the exact specifications called out in Honda's own parts catalog, ensuring a correct fit wherever it is called for on these machines. Buyers should confirm their unit's serial number against the fitment table to verify this is the right nut for their specific production run.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, so thread pitch, across-flat dimensions, and bearing face geometry match the original hardware exactly.
- Left-Hand Thread Variant — this nut carries a left-hand thread designation; confirm your application requires a left-hand nut before ordering to avoid fitment issues.
- Broad H-Series Coverage — listed for the H3011, H3013, H4013, H4514, H4518, H5013, H5518, and RT5000 riding mowers and tractors, covering Honda's H-series and RT-series lineup.
- Serial Number Verification Recommended — Honda updates fastener specifications at production breaks, so cross-check your machine's serial number against the fitment table before ordering.
A hexagon nut is a standard threaded fastener used throughout Honda's riding mower and tractor platforms to clamp and retain components in assembly. The left-hand thread on this nut is intentional — it is used in applications where normal right-hand rotation of a shaft or spindle would otherwise cause a standard nut to loosen over time. Using the correct thread direction is essential: installing a right-hand nut in a left-hand application will allow it to back off during operation, while forcing the wrong nut risks damaging threads and leaving the fastened assembly insecure.
