Multiquip 2023458 3/8"-16 x 2 UNC Stud

The Multiquip 2023458 is a genuine OEM 3/8"-16 x 2 UNC Stud designed for MQ Diaphragm Pumps and STOW Diaphragm Pump models including the SDP-2 and SDP-3. As a factory-sourced component, this stud is manufactured to the exact thread form, length, and material specification required by the original equipment design. Verified fitment spans the MQ-D206H, SDP-2, CA90749, and SDP-3 platforms, making 2023458 a reliable choice when servicing diaphragm pump assemblies across the Multiquip portfolio.

Key Features

• Genuine OEM Thread Integrity — Manufactured to the exact 3/8"-16 UNC thread specification, ensuring proper torque engagement and a secure, metal-to-metal connection without thread mismatch.
• Direct Bolt-In Replacement — Matches the original stud length of 2 inches, dropping straight into existing bores and mating hardware without rework or shimming.
• Broad Diaphragm Pump Fitment — Confirmed for MQ-D206H, SDP-2, CA90749, and SDP-3 diaphragm pump models across the Multiquip and STOW product lines.
• Structural Fastening Confidence — A correctly specified stud maintains proper clamping load across pump housing joints, preventing fluid leaks and premature gasket or diaphragm failure.
• Fluid System Safety — In pump applications, a damaged or incorrect fastener can compromise housing seals and allow uncontrolled fluid discharge; using the correct OEM stud keeps the assembly sealed to spec.

A stud is a headless threaded fastener used to clamp pump housing sections, valve plates, or cover assemblies together with consistent, measured torque. In diaphragm pump applications, studs anchor the pump body joints that contain fluid pressure through each stroke cycle — if a stud is stretched, cross-threaded, or undersized, the clamping force drops and the joint can weep or fail under load. Replacing a worn or damaged stud with the correct OEM part restores the full clamping specification and keeps the pump performing as intended.
