As a direct Honda OEM component, this flange bolt is manufactured to the exact dimensions and thread specification of the original, ensuring a proper fit across the outboard models listed.

Key Features
- Genuine OEM Hardware — sourced directly from Honda, this flange bolt meets the same dimensional and thread specification as the original fastener installed at the factory.
- Integrated Flange Design — the built-in flange distributes clamping load evenly across the mating surface, maintaining consistent holding force in a marine environment.
- Broad Outboard Fitment — listed for Honda outboard motors including the BF40, BF115, BF250, and BF350, among others; always verify against your motor's serial number using the fitment table.
- Serial-Range Verification Recommended — Honda updates hardware specifications across production runs, so check your outboard's serial number against the compatibility table to confirm this is the correct bolt for your motor.
A flange bolt combines a standard hex bolt with an integral wide-bearing flange beneath the head, eliminating the need for a separate flat washer and distributing clamp load over a broader area. In outboard motor applications, secure and correctly torqued fasteners are essential to keeping assemblies tight against the vibration and constant moisture exposure of marine use. A bolt that is worn, stripped, or dimensionally incorrect can allow joint movement, leading to loosening, component damage, or leaks over time.
