The Honda 90201-SB0-003 Self-Lock Nut (10MM) is a genuine OEM fastener designed for Honda H4013, H4514, and H4518 lawn tractors. As a direct Honda OEM component, this self-locking nut is manufactured to the same specifications as the original hardware installed at the factory, ensuring a correct fit without guesswork. Confirm your tractor's serial number against the fitment table before ordering to make sure part number 90201-SB0-003 is the right match for your specific unit.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this self-lock nut matches the original specification for the H4013, H4514, and H4518 lawn tractors, so there is no need to adapt or modify anything during installation.
- Self-Locking Design — the integrated locking feature resists loosening from vibration during operation, keeping fastened assemblies secure through regular use and rough terrain.
- Serial Number Verification Recommended — Honda updates hardware specifications at production serial breaks, so cross-check your tractor's serial number against the compatibility table to confirm this is the correct nut for your machine.
A self-lock nut is a standard fastener with a built-in mechanism — typically a nylon insert or a deformed thread section — that creates resistance against rotation once torqued into place. This resistance prevents the nut from backing off due to the vibration a lawn tractor generates during cutting and transport. Using the correct OEM replacement ensures the locking force and thread engagement match what Honda engineered into the assembly, maintaining the integrity of the connection over time. A loose or incorrect nut can lead to component movement and premature wear at the fastened joint.
