The Honda 90308-382-670 Flange Nut (10MM) is a genuine OEM fastener designed for Honda F401, F501, FC600, FG400, and FG500 tillers. As a direct Honda OEM component, this nut is manufactured to the exact specifications called out in Honda's parts diagrams, ensuring the correct thread pitch, flange diameter, and seating geometry for a secure, properly torqued installation. Honda supersedes hardware at serial-number breaks, so verify your tiller's serial number against the fitment table before ordering to confirm part number 90308-382-670 is the correct listing for your unit.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this flange nut matches the exact thread specification and flange bearing surface called out in Honda's tiller parts diagrams
- Integrated Flange Design — the built-in flange distributes clamping load evenly, eliminating the need for a separate flat washer and keeping the fastened joint stable under the vibration loads typical of tiller operation
- Broad Tiller Fitment — listed for the F401, F501, FC600, FG400, and FG500 tillers; confirm your serial number against the fitment table to ensure this is the correct listing for your specific unit
A flange nut combines a standard hex nut with an integrated circular flange that acts as a built-in washer. The flange spreads the clamping force over a wider surface area than a plain nut alone, which helps prevent the fastener from pulling through or distorting softer mounting surfaces and keeps the joint tight under repeated vibration. On a tiller, where the drivetrain and tines generate constant vibration during operation, correctly specified hardware like this nut is what keeps assemblies properly torqued and securely fastened over time. Using an incorrect or worn fastener can allow joints to loosen, leading to misalignment or component damage during use.
