Key Features
- Genuine Honda OEM Fastener — manufactured to Honda's dimensional specifications, delivering the thread engagement and clamping load the application requires
- 16MM Hexagon Profile — the hex size is a key match point; verify this nut's specification matches the fastener position on your engine or tractor before ordering
- Broad Outboard Fitment — listed across Honda's four-stroke outboard lineup from compact portable models through large offshore motors, including BF and BFP series, as well as the H6522 compact tractor
- Serial Number Verification Recommended — Honda supersedes hardware at production breaks, so cross-check your unit's serial number against the fitment table to confirm part number 90302-921-000 is current for your specific machine
A hexagon nut is a standard threaded fastener used to clamp and retain components by drawing them together when tightened against a mating bolt or stud. In marine and outdoor power equipment applications, maintaining proper fastener integrity is essential — a nut that is worn, cross-threaded, or incorrect in size can result in inadequate clamping force and component loosening over time. Replacing a damaged or missing fastener with the correct OEM part ensures the joint performs as Honda designed it to.
