The Honda 90225-HW1-670 Flange Bolt (6X35) is a genuine OEM fastener designed for BF75, BF90, BF100, and BFP60 outboard motors. As a direct Honda OEM part, this flange bolt matches the original specification, ensuring correct torque retention and a secure fit without any guesswork. Honda supersedes hardware at serial breaks, so confirm your outboard's serial number against the fitment table before ordering.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this flange bolt meets the exact dimensional and mechanical requirements Honda specifies for outboard motor assembly.
- Integrated Flange Design — the built-in flange distributes clamping load evenly, reducing the risk of loosening under the vibration and marine operating conditions these outboards encounter.
- Broad Outboard Fitment — listed for BF75, BF90, BF100, and BFP60 outboard motors, including both standard and portable high-thrust variants.
- Verify by Serial Number — Honda updates hardware specifications across production runs; always cross-reference your outboard's serial number with the fitment table to confirm this is the correct bolt for your unit.
A flange bolt combines a standard threaded fastener with an integrated wide-flange washer head, allowing it to bear load across a broader surface area than a plain bolt. In outboard motor assemblies, hardware of this type holds together components that must remain firmly secured through constant exposure to vibration, water, and temperature cycling. When a fastener of this type stretches, corrodes, or is replaced with an incorrect substitute, it can lead to joint movement, component misalignment, or accelerated wear of the parts it secures.
