The Wacker Neuson is a genuine OEM Hexagonal Head Cap Screw designed for the PDT2A, PDT3A, PDT2B, PDT3, PDI2A, PDI2, PDI3A, PDI3, and PD3B series diaphragm trash pumps. As a factory-sourced fastener, is manufactured to the exact dimensions and thread specification required for proper assembly and torque retention on these pump families. Wacker Neuson genuine OEM parts are produced to the same standards as the original components fitted at the factory, so you can install with confidence knowing the fit is correct the first time.
Key Features
- Correct Thread Specification: — Manufactured to the precise hex-head geometry, thread pitch, and shank dimensions specified for Wacker Neuson diaphragm pump assemblies — no guesswork on sizing.
- Genuine OEM Sourcing: — Supplied directly from Wacker Neuson's authorized parts program, ensuring material grade and tensile strength match the original fastener used on the production line.
- Broad Diaphragm Pump Compatibility: — Fits 50mm/2-inch and 75mm/3-inch diaphragm trash pump models across the PDT2, PDT2A, PDT2B, PDT3, PDT3A, PDI2A, PDI2, PDI3A, PDI3, and PD3B series.
- Secure Clamping Under Vibration: — A properly torqued fastener maintains joint integrity on pump housings and covers that are subject to constant operating vibration, preventing loosening and fluid ingress.
- Direct Drop-In Replacement: — Matches the original fastener position exactly, requiring only standard hex tooling for installation — no drilling, rethreading, or adaptation needed.
A hexagonal head cap screw is a structural fastener used to clamp and secure pump housing covers, diaphragm plates, and other bolted joints throughout a diaphragm pump assembly. Its hex-drive head allows high torque to be applied with common hand or impact tooling, which is essential for maintaining a leak-free seal across the pump's fluid chambers. When a cap screw is missing, stripped, or of the wrong specification, the clamping force across that joint is compromised — leading to diaphragm misalignment, air leaks, or pump cover separation that can put the pump out of service entirely.
