The Honda 90205-HW1-670 Flange Bolt (6x25) is a genuine OEM fastener designed for BF40, BF50, BF60, and BFP60 outboard motors. As a direct Honda OEM part, it is manufactured to the same specifications as the original hardware installed at the factory. Honda supersedes hardware at serial breaks, so confirm your outboard's serial number against the fitment table before ordering to ensure part number 90205-HW1-670 is correct for your unit. This Flange Bolt (6x25) is a straightforward, drop-in replacement with no modification needed to restore the original assembly.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this flange bolt matches the original specification for thread pitch, shank length, and flange diameter across BF40, BF50, BF60, and BFP60 outboard motors.
- Integrated Flange Design — the built-in flange distributes clamping load evenly without a separate washer, maintaining consistent holding force in marine assembly environments.
- Fitment Spans Four Models — listed for BF40, BF50, BF60, and BFP60 outboards; check your serial number against the fitment table to confirm the correct application.
A flange bolt combines a standard hex bolt with an integrated washer-like flange at the base of the head. In outboard motor assemblies, this design spreads the clamping load across a wider surface area than a plain bolt head alone, reducing the risk of the fastener pulling through or distorting the mating component. Using the correct OEM bolt ensures the thread engagement, shank length, and flange diameter all match the original assembly — a mismatched fastener can result in under-clamping, thread damage, or an insecure joint that is difficult to detect until a component works loose.
