The Honda 90501-HA0-000 Lock Washer (6MM) is a genuine OEM component designed for the H6522 compact tractor. As a Honda OEM part, it is manufactured to the same specifications as the original hardware installed at the factory. This Lock Washer (6MM) is a direct replacement for the H6522, so verify part number 90501-HA0-000 against your machine's parts diagram before ordering to confirm it is the correct hardware for your application.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, ensuring this is the same 6MM lock washer originally installed on the H6522 compact tractor
- Exact-Fit Replacement — matched to Honda's specifications for the H6522, so installation is straightforward using the original fastener position
- Check Your Serial Number — Honda periodically supersedes hardware across production runs; confirm part number 90501-HA0-000 against your H6522 serial number in the fitment table before ordering
A lock washer is a small but important piece of fastener hardware that sits beneath a nut or bolt head to resist loosening caused by vibration and operational movement. On equipment like the H6522 compact tractor, which is subject to continuous vibration during use, standard fasteners can work themselves loose over time without the added resistance a lock washer provides. Replacing a worn or damaged lock washer with the correct OEM part helps maintain the clamping integrity of the fastened joint.
