Confirm part number 90337-V09-A01 against your tractor's parts diagram before ordering to ensure it matches your application.
Key Features
- Genuine OEM Honda — sourced directly from Honda, matching the original thread pitch and locking profile specified for HA4118 and HA4120 lawn tractors
- #10-24 Thread Specification — the (#10-24) designation identifies the exact size; verify this matches your parts diagram before ordering
- Self-Locking Design — the locking feature resists loosening under vibration, keeping fastened assemblies secure during operation
- Serial Number Awareness — Honda updates parts at serial breaks, so cross-check your tractor's serial number against the fitment table to confirm this is the correct supersession for your unit
A self-lock nut is a standard threaded fastener with an integrated locking element — typically a nylon insert or a deformed thread section — that grips the mating bolt or stud and resists backing off under vibration or load. On lawn tractors like the HA4118 and HA4120, fasteners like this one are used throughout the machine wherever a connection must stay tight during operation over uneven terrain. When a self-lock nut loses its locking effectiveness — through reuse, over-torquing, or wear — the joint it secures can work loose, leading to play or misalignment in the assembly it holds. Replacing it with the correct Honda OEM part restores the original clamping integrity.
