The Wacker Neuson is a genuine OEM Socket Head Cap Screw designed for the PT6LT and PT6LS series 6-inch centrifugal trash pumps. As a direct Wacker Neuson OEM part, the is manufactured to the same specifications as the original fastener, ensuring a correct and consistent fit across PT6LT and PT6LS pump configurations including trailer-mounted, skid-mounted, and Tier 4 variants. Whether you're servicing a PT6LT Pump with Trailer, a PT6LS Skid Mounted unit, or an import-model PT6LS(I) or PT6LT(I), this is the specified replacement fastener for those assemblies.
Key Features
- Genuine OEM Fastener Grade — Sourced directly from Wacker Neuson, this socket head cap screw meets the exact torque and tensile specifications required for pump assembly integrity on 6-inch trash pump models.
- Hex Socket Drive Design — The recessed hex socket head allows for high-torque installation with an Allen/hex key in confined pump housing areas where a standard bolt head would be impractical.
- Broad PT6 Series Coverage — Fits PT6LT (trailer-mounted), PT6LS (skid-mounted), PT6LT T4, PT6LS(I), and PT6LT(I) configurations, making it a single correct fastener across the PT6 pump family.
- Maintains Pump Housing Integrity — A properly torqued and correctly specified cap screw keeps pump covers, volutes, and access panels securely seated, preventing vibration-induced loosening under continuous high-flow pumping conditions.
- Exact OEM Part Number Reference — Part number 5000077823 is the Wacker Neuson factory-designated fastener for these assemblies, eliminating guesswork when ordering a replacement.
A socket head cap screw is a threaded fastener with a cylindrical head and an internal hex drive socket, designed to be driven by an Allen key or hex bit rather than an external wrench. On large-capacity trash pumps like the PT6LT and PT6LS, these fasteners are commonly used to secure pump housings, volute covers, and access panels where space is limited and high clamping force is required. Using the correct OEM-specified fastener ensures proper thread engagement and torque retention — a stripped, undersized, or incorrect-grade screw in a high-vibration pump application can lead to loose assemblies, leaks, or component damage over time.
