The Honda 90505-ZA1-811 Spring Washer (6mm) is a genuine OEM fastener component designed for Honda EW140, EW170, EW171, and EXW171 welder generators. As an authentic Honda OEM part, this washer is sourced directly through Honda's parts supply chain, ensuring it matches the original specification used on the production line. Confirm your unit's serial number against the fitment table before ordering, as Honda periodically supersedes parts at serial breaks across its welder generator lineup.
Key Features
- Genuine OEM Consistency — sourced directly from Honda, this Spring Washer (6mm) matches the original fastener used in Honda EW-series welder generator assembly, so fitment is exact
- Direct OEM Replacement — drops in as a like-for-like replacement with no reworking of the surrounding hardware, keeping your reassembly straightforward
- Welder Generator Fitment — listed for the EW140, EW170, EW171, and EXW171 welder generators; verify your serial number against the fitment table to confirm the correct part for your unit
- Fastener Integrity — a spring washer maintains clamping load under vibration; a worn or flattened one can allow fasteners to work loose during operation, making timely replacement worthwhile
A spring washer is a small, split-ring fastener component that sits beneath a nut or bolt head to maintain tension in a bolted joint. As the machine vibrates during use, the washer's spring action resists loosening by continuously exerting load against the mating surfaces. When a spring washer loses its tension or becomes deformed, the fastener it supports can gradually back out, potentially allowing assembled components to shift or rattle. Replacing a worn spring washer with the correct OEM part is a straightforward step that helps keep bolted assemblies secure on Honda EW140, EW170, EW171, and EXW171 welder generators.
