The Multiquip EM402439 1/2 x 3 5/16 In Stud is a genuine OEM fastener designed for MG30 series fireproofing pumps and mixers, including the MG30T2D, MG30M2D, MG30T3D, MG30M3D, and MG30. As a direct OEM replacement sourced from Multiquip, EM402439 matches the original specification for material grade, thread pitch, and overall length — ensuring a proper, secure connection without the guesswork. DHS Equipment supplies this stud as part of their verified Multiquip OEM parts catalog, so you can be confident you are receiving the correct component for your machine. Cross-reference your model code and parts diagram before ordering to confirm this is the right stud for your application.
Key Features
- OEM-Grade Fastener Integrity — Manufactured to the same thread pitch, shank diameter, and length specification as the original stud, ensuring full thread engagement and proper clamping load.
- Exact-Dimension Replacement — The 1/2 x 3 5/16 In sizing matches the original mounting configuration on MG30 series equipment, allowing the stud to seat and torque correctly without rework.
- Broad MG30 Series Coverage — Confirmed fitment across the MG30T2D, MG30M2D, MG30T3D, MG30M3D, and MG30 fireproofing pumps and mixers.
- Structural Holding Power — A correctly installed stud maintains critical joint integrity on pump and mixer assemblies; a worn, stripped, or incorrect stud can compromise clamping force and lead to component loosening under operating vibration.
- Genuine Multiquip OEM Part — Sourced directly through the Multiquip OEM supply chain, carrying the part number EM402439 for straightforward cross-referencing against your service manual or parts diagram.
A stud is a headless, externally threaded fastener that remains permanently installed in one component while a nut is threaded onto the exposed end to clamp a mating part in place. On MG30 series fireproofing pumps and mixers, studs like this part are commonly used at high-load joint faces — such as pump housings, flanges, or cover plates — where a bolt would not provide adequate thread engagement or serviceability. When a stud becomes corroded, stripped, or damaged, the joint it secures can work loose under the vibration and pressure of normal pump or mixer operation, potentially causing leaks, misalignment, or component damage. Replacing a failed stud with the correct OEM part restores the joint to its designed clamping specification.
