Wacker Neuson 5100075503 1/4-20x1 Screw

The Wacker Neuson is a genuine OEM 1/4-20x1 Screw designed for the PDT3A, PDI3A, PDI3A(I), PDT2A, and PDI2A(I) pump series. As a factory-sourced fastener, this screw is manufactured to the exact thread spec, head type, and length required by Wacker Neuson engineers — so it installs the same way the original did, every time. Stocking the correct hardware on hand keeps your pump service jobs moving without hunting down substitute fasteners that may not seat correctly. Confirm your model number against the fitment list before ordering to ensure a direct match.

Key Features

• Correct Thread Spec, Every Time — Manufactured to 1/4-20 thread standard at 1-inch length, matching the original fastener's engagement depth and torque requirements.
• Genuine OEM Sourced — Supplied directly by Wacker Neuson, this screw meets the same dimensional and material standards used in original pump assembly.
• Broad Pump Series Coverage — Fits PDT3A, PDI3A, PDI3A(I) Pump Diaphragm, PDT2A, and PDI2A(I) Pump models, covering multiple units in the Wacker Neuson diaphragm and trash pump lineup.
• Drop-In Hardware Replacement — Threads directly into existing mounting points with no reworking or modification to surrounding components.
• Prevents Loosening and Misalignment — A worn, stripped, or incorrect screw can allow panels, covers, or pump components to shift under vibration — proper hardware keeps assemblies secure and seated.

A 1/4-20x1 screw is a standard coarse-thread fastener used throughout pump assemblies to secure covers, housings, and internal components. While small in size, the correct screw ensures proper clamping force and thread engagement, which is critical on equipment that operates under continuous vibration. Using an incorrect length or thread pitch can result in stripped threads, loose assemblies, or fastener failure during operation — making it worth sourcing the exact replacement rather than a general hardware store substitute.
