The Honda 94021-08000-0S Cap Nut (8MM) is a genuine OEM fastener designed for a range of Honda tillers, lawn mowers, and two-stage snow blowers. This part is sourced directly from Honda, ensuring an exact match to the original hardware used in production. It is listed for models including the FR500, FR600, FR700, and FR800 tillers, the HR17, HR173, HRM21, and HRS21 lawn mowers, and the HS1336 and HSM1336 two-stage snow blowers — verify your machine's serial number against the fitment table to confirm the correct application before ordering. Replacing a worn, stripped, or missing cap nut with the correct OEM part keeps the assembly properly secured and maintains the integrity of the fastened joint.
Key Features
- Genuine Honda OEM Hardware — identical to the cap nut fitted at the factory, with correct thread pitch and cap profile for a proper 8MM engagement
- Broad Equipment Coverage — listed for Honda FR-series tillers, HR-series and HRM/HRS lawn mowers, and HS/HSM two-stage snow blowers, including the FR500, FR700, HR173, HRS21, HS1336, and HSM1336
- Serial Number Verification Recommended — Honda updates fastener specifications at production breaks, so confirm your machine's serial number against the fitment table before ordering
- Direct OEM Replacement — installs without modification; matches the original hardware spec so the joint seats and torques correctly
A cap nut combines a standard threaded nut with a closed, domed end that covers the exposed tip of a bolt or stud. This design secures the joint in the same way as an open hex nut while protecting the exposed thread from damage, contamination, and corrosion. When a cap nut becomes stripped, cracked, or lost, the fastened assembly can work loose under vibration — replacing it promptly with the correct OEM part restores a secure, properly torqued connection.
