The Honda 90304-VP7-003 Self-Lock Nut (8MM) is a genuine OEM fastener designed for the HRM3000, HRM310, and HRM520 robotic mowers. As a direct Honda OEM component, this nut is manufactured to the same specification as the original hardware installed at the factory. Confirm the part number 90304-VP7-003 against your mower's parts diagram before ordering, as Honda periodically updates part assignments at production serial breaks.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, ensuring the self-locking thread geometry matches the original hardware on your robotic mower
- Direct OEM Replacement — replaces part number 90304-VP7-003 with no re-tapping, reworking, or adaptation of the mating threads
- Broad Miimo Compatibility — listed for HRM3000, HRM310, and HRM520 robotic mowers; check your serial number against the fitment table to confirm the correct application
A self-locking nut incorporates a locking feature — typically a nylon insert or a deformed thread section — that resists loosening under the vibration and movement a robotic mower generates during normal operation. Unlike a standard hex nut, it maintains clamping force without requiring a separate lock washer. When the locking element wears or the nut is overtightened and the locking action is compromised, the fastened joint can work loose, which may affect the alignment or retention of the component it secures. Replacing a worn self-lock nut with a fresh OEM unit restores the intended clamping integrity at that joint.
