The Honda 90315-V09-A01 Lock Nut (3/4"-16) is a genuine OEM fastener designed for the HA4118 lawn tractor. As a direct Honda OEM component, this lock nut is the correct specification for the application, eliminating the guesswork that comes with sourcing generic hardware. Confirm your serial number against the fitment table to ensure part number 90315-V09-A01 is the right match for your unit before ordering.
Key Features
- Genuine Honda OEM Fastener — sourced directly from Honda, this lock nut carries the correct thread specification (3/4"-16) and locking geometry for the HA4118 lawn tractor application.
- Exact Thread Match — the 3/4"-16 thread pitch is a specific designation; using a mismatched fastener risks improper seating and joint failure, making an OEM-matched replacement the right call.
- Serial Number Verification Recommended — Honda supersedes fastener part numbers across production runs, so check your tractor's serial number against the fitment table to confirm this is the correct lock nut for your machine.
A lock nut is a fastener engineered to resist loosening under vibration and dynamic loads — conditions that are constant on a working lawn tractor. Unlike a standard hex nut, a lock nut incorporates a locking feature that maintains clamping force even as the machine cycles through operation. When a lock nut loosens or is replaced with an incorrect substitute, the joint it secures can work free over time, leading to component movement or separation. Using the correct OEM specification nut keeps the joint torqued to the intended clamping load.
