The Multiquip EM136 Stud 3/4-16X8 is a genuine OEM fastener designed for Mayco concrete pump models C30HD, C30HDNI, C30HDN, C30HDG, C30HDZ, and C30HDGA. As a direct OEM replacement, this stud is manufactured to the exact thread pitch and dimensional spec required for a correct, secure fit in the pump assembly. DHS Equipment sources this part directly through authorized Multiquip distribution channels, so you can order with confidence knowing you're getting the right hardware the first time.
Key Features
- Genuine OEM Thread Specification — Manufactured to the exact 3/4-16 thread pitch and 8-inch length required by the C30HD pump assembly, ensuring full thread engagement and correct clamping load.
- Direct OEM Replacement — Installs in place of the original stud without modification, maintaining the correct bolt pattern and torque characteristics of the fastened joint.
- Broad C30 Series Compatibility — Fits C30HD, C30HDNI, C30HDNI Precision, C30HDNI Zenith, C30HDN, C30HDG, C30HDZ, and C30HDGA Mayco concrete pump models.
- Structural Integrity Under Load — A correctly specified stud maintains the clamping force needed to keep critical pump components sealed and properly aligned during high-pressure concrete pumping operations.
- Pressure System Safety — Using the correct stud length and thread pitch in a concrete pump is essential to maintaining joint integrity; an incorrect or worn stud can compromise sealing and allow dangerous pressure loss.
A stud is a headless threaded fastener that is permanently anchored into a housing or structural component on one end, with the exposed threaded end accepting a nut to clamp mating parts together. In a concrete pump like the C30HD series, studs are commonly used to secure critical assemblies such as pump housings, manifolds, and cover plates where repeated serviceability is required. When a stud stretches, strips, or breaks, it compromises the clamping load on the joint, which can lead to leaks, misalignment, or structural failure of the fastened assembly — making timely replacement with the correct OEM part essential to keeping the pump operating safely and efficiently.
