The Honda 90103-V09-A01 Flange Bolt (8X45) is a genuine OEM fastener designed for the HA4118 and HA4120 lawn tractors. Sourced directly from Honda, this bolt carries the exact dimensions and thread specification Honda engineers chose for these machines, so it drops into place without modification. Verify your tractor's serial number against the fitment table below before ordering, as Honda periodically supersedes hardware at production breaks.
Key Features
- Genuine OEM Hardware — manufactured to Honda's own specification for the HA4118 and HA4120 lawn tractors, ensuring correct thread form and head dimensions every time
- Exact Dimensional Fit — the 8 mm diameter and 45 mm length match the original fastener, so this bolt seats and torques properly without any rework
- Serial Number Verification Recommended — Honda updates hardware specifications at production breaks, so confirm your tractor's serial number against the compatibility table to be certain part number 90103-V09-A01 is the right call for your unit
A flange bolt combines a standard hex bolt with an integrated flanged washer beneath the head. The flange distributes clamping load across a wider surface area than a plain bolt head alone, reducing the risk of the fastener loosening or pulling through a mounting point during operation. On lawn tractors like the HA4118 and HA4120, using the correct OEM fastener in every position keeps assemblies clamped to specification — a worn, incorrect, or under-length bolt can allow movement where none is intended.
