The Honda 90105-881-000 Hexagon Bolt (6X12) is a genuine OEM fastener designed for Honda BF-series four-stroke outboard motors, including the BF115, BF130, BF135, BF140, BF150, BF200, BF225, BF250, BF350, BF15, BF25, BF30, BF35, BF40, BF45, BF50, BF75, BF8, BF9, BF90, BFP8, and BFP9. Sourced directly from Honda, this bolt matches the exact dimensions and specification of the original hardware it replaces. Confirm your outboard's serial number against the fitment table before ordering, as Honda updates fastener specifications at production breaks across its outboard lineup.
Key Features
- Genuine OEM Honda Hardware — manufactured to Honda's own specification for the BF-series outboard range, ensuring correct thread form and head geometry for a proper installation.
- Exact Dimensional Match — the 6 mm diameter by 12 mm length of this bolt is engineered to the original design, so it seats fully and clamps consistently without shimming or modification.
- Broad BF-Series Coverage — listed for Honda outboard motors including models from the BF8 portable up to the BF350, covering portable and full-size outboards alike.
- Serial Number Verification Recommended — Honda supersedes fastener part numbers at production milestones, so cross-check your outboard's serial number against the compatibility table to confirm this is the correct bolt for your unit.
A hexagon bolt is a standard threaded fastener used throughout Honda outboard motors to secure components within the powerhead, mid-section, and lower unit assemblies. The 6 mm by 12 mm sizing — 6 mm thread diameter, 12 mm shank length — determines where in the outboard it is used, and installing a bolt of the wrong length or thread pitch can result in under-clamping or thread damage. Using the correct OEM replacement ensures the joint holds to the same clamping load the outboard was built with, keeping critical components properly retained through the vibration and load cycles of normal marine operation.
