The Honda 90101-HW1-671 Flange Bolt (8X25) is a genuine OEM fastener designed for Honda BF25, BF30, BF40, BF50, BF60, and BFP60 outboard motors. As a direct Honda OEM part, it is manufactured to the exact dimensions and tolerances specified for these outboards, ensuring a proper fit without guesswork. If you are sourcing this bolt by part number 90101-HW1-671, confirm your outboard's serial number against the fitment table before ordering, as Honda periodically supersedes hardware at serial breaks.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, this bolt meets the exact thread pitch, shank diameter, and flange dimensions specified for Honda outboard applications.
- Integrated Flange Design — the built-in flange distributes clamping load evenly, eliminating the need for a separate washer and maintaining consistent holding force at the joint.
- Broad Outboard Coverage — listed for BF25, BF30, BF40, BF50, BF60, and BFP60 outboard motors; verify your serial number against the fitment table to confirm the correct application.
- Direct Honda Replacement — replaces the original hardware with an identical-spec bolt, so reassembly proceeds exactly as Honda designed it.
A flange bolt combines a standard bolt with an integral flanged collar that acts as a load-spreading bearing surface. In an outboard motor, fasteners like this are used throughout the powerhead, midsection, and lower unit to secure components against the constant vibration and stress of marine operation. Using the correct OEM-spec bolt matters because an undersized or incorrect-grade fastener can work loose or fail to maintain proper clamping force, leading to joint movement or component damage over time.
