The Honda 93700-05040-4J Oval Screw (5X40) is a genuine OEM fastener designed for BF40 and BF50 outboard motors. Sourced directly from Honda, this screw matches the exact dimensions and head geometry specified for these motors, ensuring a flush, secure fit in every application. Confirm your motor's serial number against the fitment table before ordering to ensure this is the correct fastener for your unit.
Key Features
- Genuine Honda OEM Hardware — an authentic Honda part manufactured to the same specification as the original, so it seats and torques correctly without rework.
- Oval Head Profile — the oval head geometry delivers a low-profile, flush finish suited to the panel and cover assemblies found on BF40 and BF50 outboards.
- Direct OEM Replacement — part number 93700-05040-4J replaces the original screw with no modification, keeping the assembly intact.
- Check Your Serial Number — Honda updates fastener specifications at serial-number breaks, so verify your motor's serial number against the fitment table to confirm this is the right screw for your application.
An oval screw is a threaded fastener with a domed, low-profile head that sits flush or slightly proud of the surface it secures, reducing snagging and presenting a clean finish on exposed panels and covers. On BF40 and BF50 outboard motors, fasteners like this one hold trim panels, covers, and other assemblies in place through the vibration and moisture exposure that marine operation demands. Using the correct OEM screw ensures the head seats properly in its recess and that the thread engagement meets Honda's original design intent — a mismatched fastener can strip threads, leave gaps in a cover seal, or work loose over time.
