The Honda 94021-06020 Cap Nut (6MM) is a genuine OEM fastener used across a wide range of Honda engines, generators, lawn mowers, snow blowers, power carriers, outboard motors, and other equipment, including GX360 horizontal shaft engines, EM5000 and EL5000 generators, GV35 vertical shaft engines, HS50, HS55, HS70, HS80, HS624, HS724, HS828, HS928, HS1132, and HS1332 two-stage snow blowers, HR17, HR21, and HRA21 lawn mowers, HP250 and HP400 power carriers, BF2, BF9, BF15, and B75 portable outboard motors, and the HT3810 lawn tractor. As a genuine Honda OEM component, this Cap Nut (6MM) is manufactured to the same specification as the fastener that left the factory, ensuring a correct thread engagement and a flush, finished cap profile every time. Always confirm your machine's serial number against the fitment table before ordering, as Honda may revise hardware at production breaks.
Key Features
- Genuine OEM Honda Fastener — sourced directly from Honda, this Cap Nut (6MM) meets the exact thread specification and cap geometry of the original hardware it replaces.
- Broad Cross-Equipment Fitment — listed for Honda engines, generators, snow blowers, lawn mowers, portable outboards, power carriers, and a lawn tractor; use the fitment table to confirm your specific model and serial range.
- Capped Profile — the domed cap end covers and protects the exposed thread end of the fastener, providing a clean finished appearance at the fastened joint.
- Serial Number Verification Recommended — Honda updates hardware specifications at serial number breaks, so check your machine's serial number against the compatibility table to confirm this is the correct part for your unit.
A cap nut is a standard hex nut with one closed, domed end that covers the exposed tip of the bolt or stud it threads onto. This closure protects the thread end from contamination and gives the fastened joint a smooth, finished surface. When a cap nut is worn, cross-threaded, or missing, the exposed thread beneath it is left vulnerable, and the clamping integrity of the joint it secures is compromised. Replacing a damaged or lost cap nut with the correct genuine OEM part restores proper thread engagement and the clean cap profile Honda intended at that fastened point.
