The Wacker Neuson Setscrew is a genuine OEM fastener designed for the PT6 series self-priming centrifugal trash pumps, including PT6LT, PT6LS, PT6Y, PT6YT, and PTK6 models. As a direct OEM replacement, this setscrew is manufactured to the same specifications as the original hardware installed at the factory, ensuring correct torque engagement and a secure fit within the pump assembly. It is compatible across a wide range of PT6 configurations, including trailer-mounted, skid-mounted, and EPA T4-compliant variants. Keep a spare on hand to avoid unnecessary delays during routine service or field repairs.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the exact material hardness and thread specification of the original setscrew, ensuring full engagement and consistent clamping force in pump assembly applications.
- Drop-In Installation — Matches the original thread form and drive type for tool-compatible installation without rework or modification to existing hardware seats.
- Broad PT6 Series Coverage — Fits PT6LT, PT6LS, PT6Y, PT6YT, and PTK6 trash pump variants, including trailer-mounted, skid-mounted, and EPA T4 configurations.
- Maintains Structural Integrity — A correctly seated setscrew locks critical rotating or stationary components in position; a loose or damaged one can allow unwanted movement, leading to accelerated wear or component failure.
- Verified OEM Part Number — Sourced directly through Wacker Neuson's authorized parts supply chain, so you receive exactly the part called out in the machine's service documentation.
A setscrew is a small but critical fastener used to secure a component — such as a shaft, collar, or fitting — in a fixed position within an assembly without the use of a protruding head. In trash pump applications like the PT6 series, setscrews are used to lock rotating or mounted components firmly in place, preventing slippage under load or vibration. When a setscrew becomes stripped, corroded, or loses its seating torque, the affected component can shift during operation, causing misalignment, increased wear on mating parts, or a complete loss of function in the assembly it supports.
