The Multiquip AO100500175 is a genuine OEM Screw, 1/2"-13 x 1-3/4" HX designed for STOW Diaphragm Pump models SDP-2, SDP-3, and CA90749. As a factory-sourced fastener, it delivers the exact thread pitch, shank length, and head geometry specified for these pumps — ensuring a proper, secure fit without guesswork. This screw is a direct OEM replacement, meaning it matches the original hardware installed at the factory for verified compatibility across the STOW Diaphragm Pump series.
Key Features
- OEM-Spec Thread Dimensions: — Cut to the exact 1/2"-13 UNC thread standard and 1-3/4" length specified for STOW Diaphragm Pump assemblies, so fastener engagement and clamping load are correct from installation.
- Genuine Multiquip Part: — Sourced directly from Multiquip as an OEM component, ensuring the material grade and hex head dimensions match the original hardware on these pumps.
- Confirmed Fitment: — Verified for use on STOW Diaphragm Pump models SDP-2, SDP-3, and CA90749 by part number AO100500175.
- Structural Integrity at the Joint: — A correctly sized and torqued fastener keeps pump housings, covers, and mounting points properly sealed and aligned; an undersized or incorrect screw can allow flex, leaks, or loosening under vibration.
- Leak Prevention Compliance: — On diaphragm pump assemblies, fastener integrity directly affects fluid containment; using the specified OEM screw maintains the clamping force needed to keep gaskets and diaphragms properly seated.
A hex screw in a diaphragm pump assembly does more than simply hold components together — it provides the clamping force that compresses gaskets and diaphragm interfaces, keeping the pump fluid-tight under operating pressure and vibration. When a fastener is stripped, corroded, or replaced with an incorrect size, clamping force is compromised and leaks or housing misalignment can result. Using the correct OEM-specified screw, such as AO100500175, ensures the joint performs as engineered throughout the service life of the pump.
