The Wacker Neuson Socket Head Screw is a genuine OEM socket head screw designed for PTS4V and PTK4 series centrifugal trash pumps. As a factory-sourced component, this screw is manufactured to the exact dimensions and grade specifications Wacker Neuson requires for proper assembly and torque retention across all covered pump configurations. Fitment is confirmed for multiple PTS4V and PTK4 variants, including the PTS4V(I) and PTK4(I) pump kits. When you need a direct, hassle-free replacement, sourcing the correct OEM hardware ensures your pump goes back together the way it left the factory.
Key Features
- OEM-Grade Fastener Integrity — Manufactured to the exact thread pitch, head geometry, and tensile grade specified by Wacker Neuson, so clamping force and torque values hold up under pump operating loads.
- Hex Socket Drive for Tight Spaces — The recessed socket head design allows Allen/hex key installation in the confined pump housing areas where a standard bolt head won't fit.
- Broad PTS4V and PTK4 Series Coverage — Compatible with PTS4V, PTS4V(I), PTK4, and PTK4(I) centrifugal trash pump models, covering both standard and kit configurations.
- Maintains Pump Structural Integrity — A properly torqued socket head screw keeps pump covers, volutes, and internal assemblies sealed and secure; a worn or incorrect fastener risks loosening under vibration and allowing leaks or component separation.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM parts network, ensuring the part number 5100040900 you receive matches the original component exactly.
A socket head screw is a precision fastener that uses an internal hexagonal recess to transfer torque cleanly during installation, allowing higher clamping loads in tighter spaces than a standard hex head bolt. In a centrifugal trash pump, these screws hold critical assemblies — such as pump covers, wear plates, and volute housings — together under continuous vibration, fluid pressure, and the mechanical stress of moving solids-laden water. A damaged, stretched, or incorrect replacement screw can back out over time, compromising housing integrity, allowing water ingress, and ultimately causing pump failure or unsafe operation.
