Key Features
- Genuine OEM Hardware — sourced directly from Honda, manufactured to the same specification as the original fastener installed at the factory.
- Broad Fitment Across Honda Catalogues — listed for Honda horizontal and vertical shaft engines, conventional generators, the FR700 tiller, and Honda riding mowers and lawn tractors.
- Serial Number Verification Recommended — Honda supersedes hardware at production breaks, so confirm your machine's serial number against the fitment table before ordering.
A nut is a fundamental threaded fastener that pairs with a bolt or stud to clamp and secure components together, maintaining the structural integrity of an assembly under vibration and load. On equipment that runs for extended hours, original-specification hardware ensures the correct thread engagement and clamping force are maintained. A worn, stripped, or incorrect-grade nut can allow fastened components to work loose over time, making like-for-like replacement with a genuine Honda part the straightforward choice during any service or repair.
