The Multiquip 2025169 is a genuine OEM Hex Screw 5/16"-18 UNC x 2" designed for MQ Diaphragm Pumps and STOW Diaphragm Pumps, including the SDP-2, SDP-3, CA90749, and MQ-D206H series. As a factory-sourced fastener, it meets the original torque and thread specifications called out in the equipment design. Sourced directly through authorized Multiquip channels, this screw is an exact match for the original hardware, so installation is straightforward with no guesswork on thread pitch or grip length.
Key Features
- Correct Thread Specification — 5/16"-18 UNC x 2" threading matches the original fastener spec, ensuring proper engagement depth and clamp load across pump housing joints.
- Genuine OEM Hardware — Factory-sourced from Multiquip, this screw is manufactured to the same material grade and dimensional tolerance as the part it replaces.
- Broad Diaphragm Pump Fitment — Compatible with MQ-D206H, SDP-2, SDP-3, and CA90749 models across both MQ and STOW diaphragm pump lines.
- Structural Integrity at the Pump Housing — Fasteners in diaphragm pump assemblies secure critical housing sections under cyclic pressure; using the correct screw prevents loosening, leaks, and premature seal failure.
- Drop-In Replacement — Identical hex drive configuration to the original, so existing tooling fits without any modification to the pump assembly or mounting surfaces.
This hex screw serves as a structural fastener within the diaphragm pump assembly, holding housing sections, covers, or mounting brackets together under continuous pumping cycles. Because diaphragm pumps operate with repetitive pressure pulses, fasteners in these assemblies are subject to vibration and cyclic loading — a screw that is the wrong length, thread pitch, or material grade can back out or fail to clamp correctly, leading to housing leaks or component misalignment. Using the correct Multiquip 2025169 Hex Screw 5/16"-18 UNC x 2" keeps the assembly sealed and secure through demanding pump operation.
