Key Features
- Genuine OEM Hardware — sourced directly from Honda, this self-locking nut meets the same specification as the fastener originally installed on HT4213 and MM46 tractors.
- Self-Locking Design — the locking feature resists loosening under vibration and operational loads, maintaining secure fastening over time.
- Check Your Serial Number — Honda updates hardware specifications at production serial breaks; always verify your machine's serial number against the compatibility table to confirm this is the correct nut for your unit.
A self-lock nut is a fastener with a built-in locking mechanism — typically a distorted thread or nylon insert — that resists backing off under vibration. On tractors such as the HT4213 and MM46, self-locking nuts are used wherever a standard nut could work loose during operation, compromising the integrity of the assembly it secures. Using the correct OEM nut ensures the locking action performs as Honda intended; a mismatched or worn fastener may not hold torque reliably over time.
