The Wacker Neuson Screw M4 X 40 With Washer is a genuine OEM fastener designed for the GPi3200, GPSi3200, GPi4300, and GPSi4300 portable inverter generator series. As a factory-sourced component, part is manufactured to the exact dimensions and material specification Wacker Neuson requires for correct assembly and secure clamping in these units. The integrated washer eliminates the need for a separate loose washer, ensuring the correct load distribution every time the fastener is installed. If you are servicing or reassembling a GPi3200, GPSi3200, GPi4300, or GPSi4300 generator, this is the direct replacement screw your machine was built with.
Key Features
- Correct Thread and Length Specification — M4 x 40 sizing matches the original fastener exactly, so torque loads are applied correctly across the joint without under- or over-clamping.
- Integrated Washer Design — The captive washer distributes clamping force evenly across the mating surface, protecting panel material and preventing fastener pull-through during assembly.
- Genuine OEM Sourcing — Produced by Wacker Neuson as a factory part, 5000180368 meets the same material hardness and plating standards as the original hardware installed at the production line.
- Broad Inverter Generator Coverage — Fits multiple configurations across the GPi3200, GPSi3200, GPi4300, and GPSi4300 inverter generator families, covering a wide range of serial-number variants within those series.
- Secure Panel and Component Retention — A correctly torqued, correctly sized screw keeps housings, covers, and internal brackets firmly seated — a loose or wrong-size fastener can lead to vibration damage or misaligned components during operation.
A screw with an integrated washer is a fastener assembly that combines a threaded screw and a bearing washer into a single captive unit. In a portable inverter generator, fasteners like the 5000180368 secure housings, brackets, and internal panels against the constant vibration produced during operation. When a screw is missing, stripped, or replaced with an incorrect size, the joint loses clamping integrity — panels can shift, vibration can accelerate wear on surrounding components, and in some cases covers may fail to seat correctly, affecting weather resistance and safety enclosure performance. Using the correct OEM replacement ensures the joint behaves exactly as Wacker Neuson engineered it to.
