The Honda 90103-426-000 Flange Bolt (8X20) is a genuine OEM fastener designed for the H5013, H5518, and RT5000 multi-purpose tractors. As a factory-sourced component, it is manufactured to the exact dimensions Honda specifies, ensuring a correct fit without the guesswork that can come with non-OEM hardware. This bolt is a direct replacement listed for all three multi-purpose tractor models, though buyers should confirm the part number 90103-426-000 against their machine's serial number to ensure they are selecting the right hardware revision for their unit. Using the correct factory fastener keeps critical assemblies properly secured and torqued to spec.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this flange bolt meets the exact thread pitch, shank diameter, and head dimensions specified for these tractors, so it seats and torques correctly
- Integrated Flange Design — the built-in flange spreads clamping load across a wider bearing surface compared to a standard bolt, reducing the risk of loosening under vibration
- Confirmed Fitment — listed for the H5013, H5518, and RT5000 multi-purpose tractors; verify your machine's serial number against the fitment table to confirm the correct revision for your unit
A flange bolt combines a standard hex bolt with an integrated washer-like flange at the base of the head. This flange distributes clamping force over a broader area than a plain bolt head alone, which helps maintain joint integrity on assemblies subject to engine vibration and operational stress. When a fastener of this type is missing, damaged, or replaced with an incorrect size, the joint it secures can work loose over time, leading to component misalignment or failure of the assembly it holds together.
