The Wacker Neuson is a genuine OEM Hex Head Screw M6 X 25 designed for the STP400, STP750, and ASP400 series submersible pumps. As a factory-sourced fastener, part number is manufactured to the exact thread pitch, head dimensions, and material grade specified for these pumps — ensuring a secure, rattle-free connection without the guesswork of finding a generic substitute. This screw is confirmed to fit multiple STP400 configurations as well as the STP750 and ASP400 models, covering a broad range of Wacker Neuson submersible pump variants. When you need to restore a pump to fully assembled condition after service, sourcing the correct OEM hardware is the straightforward way to get it done right.
Key Features
- Correct Thread and Head Spec — M6 x 25 sizing with a hex head profile matches the original fastener exactly, threading in without chasing or recutting.
- Genuine OEM Hardware — Sourced directly from Wacker Neuson, this screw is manufactured to the same material grade and torque specification as the fastener it replaces.
- Broad Submersible Pump Fitment — Confirmed for STP400, STP750, and ASP400 submersible pump models, covering multiple serial number configurations within each series.
- Maintains Pump Integrity Under Load — A correctly torqued fastener keeps housings, covers, and internal assemblies properly clamped, preventing vibration-induced loosening during continuous pump operation.
- Direct Service Replacement — Ideal for routine maintenance teardowns and field repairs where original hardware is lost, damaged, or corroded beyond reuse.
A hex head screw like the 5000071756 serves as a structural fastener that clamps and secures pump housings, motor covers, or internal component assemblies together. In a submersible pump operating under continuous wet conditions, fastener integrity is critical — a loose or incorrect screw can allow housing panels to shift, compromise sealing surfaces, and ultimately let water ingress reach sensitive motor components. When a fastener corrodes, strips, or goes missing during service, replacing it with the correct OEM part ensures the assembly is torqued and clamped to the designed specification, keeping the pump performing reliably through demanding dewatering applications.
