The Honda 90303-692-003 Self-Lock Nut (10MM) is a genuine OEM fastener designed for Honda FR500, FR600, FR700, FR800, and FRC800 tillers. As a Honda OEM part, it is manufactured to the same specifications as the hardware installed on the production line, ensuring a correct thread engagement and secure hold. Confirm your tiller's serial number against the fitment table before ordering, as Honda updates part supersessions at specific serial breaks.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, this self-locking nut delivers the same thread engagement and holding force as the original hardware on your tiller
- Self-Locking Design — the locking element resists loosening under the vibration and load cycles that Honda rear-tine tillers generate during operation, maintaining a secure connection without secondary locking hardware
- Tiller-Specific Fitment — listed for the FR500, FR600, FR700, FR800, and FRC800 tillers; verify your unit's serial number against the compatibility table to confirm this is the correct part for your machine
A self-lock nut uses an integrated locking mechanism — typically a deformed thread or nylon insert — that creates resistance against rotation, preventing the fastener from backing off under vibration. On equipment like a tiller, where the machine endures sustained ground engagement and mechanical vibration, standard nuts can gradually loosen and work free; a self-locking nut holds its clamping load across those conditions. When a self-lock nut is worn, damaged, or replaced with an incorrect fastener, the joint it secures can lose clamping force over time, leading to movement, wear, or component separation at that location.
