The Wacker Neuson Socket Head Cap Screw is a genuine OEM fastener designed for the PT3, PT3A, PT3H, PT3V, and PT6Y series self-priming centrifugal trash pumps. As a direct OEM replacement, part is manufactured to the same specifications as the original hardware, ensuring correct torque engagement and a flush, secure fit within the pump assembly. This screw is confirmed compatible across a wide range of PT3 and PT6Y configurations, including the PT6YT and PT6Y EPA T4 variants. Whether you are completing a scheduled service or rebuilding after wear, this is the correct fastener for the job.
Key Features
- Genuine OEM Hardness and Thread Specification — Manufactured to the original thread pitch, grade, and head geometry, so the screw seats and torques correctly without galling or stripping.
- Direct Drop-In Replacement — Installs in the existing pump housing bores with no reworking of the mounting points; the socket-drive head allows access in tight pump-casing clearances.
- Broad PT-Series Compatibility — Confirmed fitment across PT3, PT3A, PT3H, PT3V, PT6Y, PT6YT, and PT6Y EPA T4 series trash pumps, covering both 75 mm / 3 in and 6 in discharge families.
- Structural Integrity of the Pump Casing — A correctly torqued fastener maintains casing clamp load and volute alignment; a worn, stripped, or incorrect screw can allow casing movement, vibration-induced loosening, and premature seal failure.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, carrying the OEM part number 5000119979 for straightforward verification against your machine's parts diagram.
The socket head cap screw is a structural fastener that clamps the pump casing, volute, or cover components together under designed preload. In a centrifugal trash pump, these fasteners must maintain consistent clamping force against the pressure and vibration generated during pumping operations. If a screw is damaged, corroded, or replaced with an incorrect grade or thread specification, the joint can lose preload, allowing casing flex, internal misalignment, and accelerated wear on seals and impeller clearances. Using the correct OEM fastener preserves the mechanical integrity of the pump assembly and supports consistent output performance across the full operating cycle.
