The Honda 94021-05020-0S Cap Nut (5MM) is a genuine OEM fastener designed for BF2 and BF20 portable outboard motors. Sourced directly from Honda, this part carries the exact dimensions and thread specification Honda engineers specified for these outboards. Honda supersedes hardware at serial breaks, so confirm your motor's serial number against the fitment table before ordering to ensure part number 94021-05020-0S is the correct listing for your unit.
Key Features
- Genuine Honda OEM Hardware — manufactured to the precise 5MM thread specification Honda requires for the BF2 and BF20, ensuring the correct fit without rework or modification.
- Outboard-Specific Fastener — listed for BF2 and BF20 portable outboard motors; verify your serial number against the fitment table to confirm this is the correct cap nut for your motor.
- Correct Clamping Integrity — a correctly fitted cap nut holds the fastened assembly securely in place; a worn, stripped, or incorrect nut can result in loosening under the vibration and load conditions an outboard motor encounters on the water.
A cap nut — sometimes called an acorn nut — is a domed fastener that threads onto a bolt or stud, covering the exposed thread end. The domed cap protects the thread from moisture, debris, and corrosion while presenting a finished appearance. On a marine outboard such as the BF2 or BF20, where components are routinely exposed to water and salt air, using the correct OEM hardware ensures the thread engagement and seating dimensions match what Honda designed for that location. A mismatched or undersized nut may not achieve full thread engagement, leading to movement or loosening over time.
