Wacker Neuson 5200012384 Truss Screw M4 x 8

The Wacker Neuson Truss Screw M4 x 8 is a genuine OEM fastener designed for the PST3 750, PSTF3 750, PS2 800, and PSA2 800 series submersible pumps. As a direct factory part, the meets the exact thread pitch, head profile, and material spec Wacker Neuson engineers specified for this application. It is a verified fit across multiple pump configurations in the PS2 and PST3 families, including 110V and 220V variants. When you need to restore a housing panel, cover, or bracket to spec, this is the part that goes back in.

Key Features

• Exact Thread Spec: — M4 x 8 dimensions match the original threaded boss precisely, so the fastener seats flush without cross-threading or over-torquing risk.
• Truss Head Profile: — The wide, low-profile truss head distributes clamping load across the mating surface, reducing the chance of deformation on pump housing panels.
• Genuine OEM Sourcing: — Sourced directly from Wacker Neuson, this screw is manufactured to the same material grade and finish as the fastener originally installed at the factory.
• Broad PST3 and PS2 Family Coverage: — A single part number covers PST3 750, PSTF3 750, PS2 800, and PSA2 800 pump variants across multiple voltage configurations, making it a practical stock item for fleets running mixed pump models.
• Structural Integrity of Pump Assembly: — A stripped, corroded, or missing fastener in a submersible pump housing can allow water ingress or panel misalignment; replacing it with the correct OEM screw keeps the enclosure sealed and properly aligned.

A truss screw is a machine fastener with a broad, rounded head and a flat underside, designed to secure panels, covers, or housings where a wide bearing surface is needed and clearance above the joint is limited. In a submersible pump like the Wacker Neuson PS2 800 or PST3 750, fasteners of this type hold critical enclosure components together under wet, high-vibration operating conditions. When a fastener fails — through corrosion, over-torquing, or simple wear — the affected panel can shift or loosen, compromising the integrity of the pump housing and potentially exposing internal components to water and debris. Replacing it promptly with the correct OEM part, the 5200012384, restores the assembly to its intended clamped condition.
