The Honda 90505-HA0-680 Washer (6X20) is a genuine OEM component designed for H3011 and H3013 riding mowers. As a factory-original part, it meets Honda's exact dimensional specifications for proper load distribution and clamping in the assembly it serves. Confirm fitment by checking your mower's serial number against the compatibility table before ordering.
Key Features
- Genuine OEM Fit — manufactured to Honda's exact dimensional spec, so the washer seats and clamps correctly without adjustment
- Riding Mower Fitment — listed for H3011 and H3013 riding mowers; verify your serial number against the fitment table, as Honda supersedes parts at serial breaks
- Direct Replacement — replaces the original washer by part number 90505-HA0-680 for a straightforward service swap
A washer of this size distributes clamping load across a wider surface area than a bolt head or nut alone can cover. This prevents fastener pull-through, reduces surface deformation on the mating component, and maintains consistent clamp force in the assembly. A washer that is undersized, worn, or missing can allow a fastener to work loose over time, leading to unwanted play or movement in the joined components.
