The Honda 90016-ZA5-000 Special Nut (5MM) is a genuine OEM fastener designed for a broad range of Honda equipment, including the BF2 portable outboard motor and Honda generators such as the EB2200, EB2500, EG1400, EG2200, EG2500, EM1600, EM1800, EM2200, EM2500, and EX2200. As a Honda OEM component, this nut is sourced directly from Honda's parts catalog and is produced to the same specifications as the original hardware installed at the factory. Confirm your model and serial number against the fitment table before ordering, as Honda updates part configurations across production runs.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this Special Nut (5MM) matches the original fastener specification for the listed machines, ensuring correct thread engagement and clamping load.
- Broad Fitment — listed for the BF2 portable outboard motor, the EB2200 inverter generator, and a wide range of Honda generators including the EG, EM, and EX series; check your model against the fitment table to confirm the correct application.
- Serial Number Verification Recommended — Honda supersedes fastener part numbers at production breaks, so verify your unit's serial number against the fitment table to confirm this is the correct nut for your machine.
A special nut differs from a standard hex nut in its geometry, thread form, or bearing surface, and Honda designates it specifically to meet the clamping or retention requirements of a particular assembly. Using the correct fastener ensures the joint holds to the torque value Honda's design calls for — an undersized or incorrect nut can back off under vibration or fail to develop the clamping force needed to keep the assembly secure. When a fastener wears, strips, or goes missing, replacing it with the correct OEM part restores the connection to its original condition.
