The Honda 90361-SM4-003 is a genuine OEM Flange Nut (8MM) designed for H2013 and H2113 lawn tractors. As a direct Honda OEM replacement, this fastener matches the original specification and installs without modification. Confirm your unit's serial number against the fitment table before ordering, as Honda updates part numbers at serial breaks — this ensures part number 90361-SM4-003 is the correct nut for your machine.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this nut meets the same standard as the original hardware used on the production line.
- 8MM Flange Design — the integrated flange distributes clamping load across a wider bearing surface, helping maintain consistent fastener tension over time.
- Tractor Fitment — listed for H2013 and H2113 lawn tractors; verify your serial number against the fitment table to confirm this is the correct replacement for your unit.
A flange nut combines a standard hex nut with a wide, washer-like base that spreads the clamping force over a broader surface area. This helps protect the mating material and keeps fastener connections secure under the vibration and load cycles a lawn tractor encounters during regular operation. A loose or missing fastener can allow components to shift or separate, so replacing worn or damaged hardware promptly keeps the machine assembled as Honda intended.
