The Honda 90349-001-000 Self-Lock Nut (8MM) is a genuine OEM fastener designed for Honda F401 and F501 tillers. As a direct Honda OEM part, this nut is manufactured to the same specification as the original hardware, ensuring correct thread engagement and holding force. This part fits both the F401 and F501 — confirm your unit's serial number against the fitment table to make sure you have the right listing for your machine.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this self-locking nut matches the original specification for thread size and locking geometry on F401 and F501 tillers.
- Self-Locking Design — the built-in locking feature resists loosening under the vibration and load cycles typical of tiller operation, maintaining fastener tension without additional locking hardware.
- Serial Number Verification Recommended — Honda updates fastener specifications at serial number breaks, so cross-check your tiller's serial number against the fitment table before ordering.
A self-lock nut uses a deformed thread section or nylon insert to create resistance against rotation, preventing the fastener from backing out due to vibration. On tillers such as the F401 and F501, which generate sustained vibration through normal soil-working operation, this locking action keeps assemblies securely fastened over time. A nut that has lost its locking torque — through wear, over-torquing, or reuse — allows fastener joints to work loose, which can lead to component movement and accelerated wear at the affected assembly.
