The Honda 90201-415-000 is a genuine OEM Cap Nut (6MM) used across a wide range of Honda engines and power equipment, including GX-series horizontal shaft engines, GXV-series vertical shaft engines, generators, tillers, lawn mowers, riding mowers, snow blowers, and water pumps. As a genuine Honda part, it is manufactured to the exact dimensions and thread specification Honda calls out for this fastener position. This Cap Nut (6MM) is a direct OEM replacement sourced from Honda's parts catalog, ensuring the correct thread pitch and cap profile for the application. Always confirm the part number 90201-415-000 against your machine's serial number and parts diagram before ordering, as Honda uses several similar fasteners across its lineup.
Key Features
- Genuine OEM Fastener — supplied directly from Honda's parts catalog to the exact thread specification and cap geometry Honda requires for this application
- 6MM Cap Nut Profile — the domed cap design covers and protects the fastener end, making it the correct replacement where a standard hex nut is not called for
- Broad Equipment Coverage — listed for GX and GXV-series engines, EG-series generators, F and FR-series tillers, HS and HSS-series snow blowers, HR-series lawn mowers, and W-series water pumps, including models such as GX160, GX390, GXV340, EG5000, WT30, and HSS1332
- Serial Number Verification Recommended — Honda supersedes fastener part numbers at production breaks, so check your machine's serial number against the fitment table to confirm this is the correct nut for your specific unit
A cap nut is a closed-end hex nut with a rounded dome on one face. The domed end covers the exposed thread of the bolt or stud it fastens, protecting the thread from debris, moisture, and mechanical damage while also providing a finished appearance. Because the cap profile is integral to the design intent in certain assembly positions, substituting an open hex nut can leave threads exposed to the operating environment. When a cap nut wears, strips, or is lost, replacing it with the correct OEM part ensures the fastener joint is restored exactly as Honda designed it.
