The Honda 90314-V09-A01 Lock Nut (3/8") is a genuine OEM replacement designed for HA4118 and HA4120 lawn tractors. As an authentic Honda part, this lock nut is held to the same standards as the original hardware installed at the factory.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, matching the original specification for HA4118 and HA4120 lawn tractors
- Locking Retention — the lock nut's built-in locking feature resists loosening under vibration and normal operating loads, keeping fastened components secure over time
- Verify Before Ordering — Honda updates part numbers at serial breaks; check your tractor's serial number against the fitment table to confirm this is the right part for your machine
A lock nut is a fastener engineered to resist self-loosening under vibration and cyclical loads — conditions that standard nuts can gradually work loose under during regular equipment use. On a lawn tractor like the HA4118 and HA4120, hardware that loses torque over time can allow components to shift or separate, affecting the tractor's operation. Replacing a worn or missing lock nut with the correct genuine Honda part restores the holding integrity of the fastened joint.
