The Honda 90403-ZG5-003 Spring Washer (10MM) is a genuine OEM component designed for the EB12 generator. Sourced directly from Honda, this washer carries the same specification as the original part installed at the factory, ensuring a correct fit without modification. When replacing hardware on the EB12, matching the exact part number 90403-ZG5-003 is the surest way to confirm you have the right size and type.
Key Features
- Genuine Honda OEM Hardware — supplied by Honda, identical in size and form to the original, so it seats and tensions exactly as intended
- Correct 10MM Sizing — the (10MM) designation identifies this specific size variant; verify it matches the fastener on your EB12 before ordering
- EB12 Generator Fitment — listed for the Honda EB12 generator; check your serial number against the fitment table to confirm this is the correct supersession for your unit
A spring washer is a split, slightly bowed ring that sits beneath a fastener. When the fastener is torqued down, the washer flexes flat, and that stored spring tension maintains clamping load as the joint experiences vibration or thermal cycling. On generator equipment like the EB12, where engine vibration is a constant, spring washers help prevent fasteners from working loose over time. A worn or flattened washer that has lost its spring no longer holds clamping force effectively, which can allow the fastener to back off gradually during operation.
