As a factory-sourced component, EM963614 is manufactured to the exact thread pitch, shank length, and head dimensions specified for these machines, ensuring proper torque retention and structural integrity in service. This bolt is sold through DHS Equipment as an authorized Multiquip replacement part, so you can order with confidence that what arrives matches what came off the machine.
Key Features
- OEM Thread and Dimensional Accuracy — Manufactured to the exact 3/4-10 thread specification and 3-inch length required by Multiquip, ensuring full thread engagement and correct clamping load.
- Direct-Fit Replacement — Drops into the same bolt positions as the original hardware with no rework or modification to mating components.
- Confirmed Fitment for C30HD and C30HDN — Verified compatible with the Mayco C30HD and C30HDN concrete pump models by Multiquip part number EM963614.
- Maintains Structural Integrity Under Load — Correct fastener grade and geometry keep pump components securely joined during high-vibration pumping cycles, preventing joint movement or fastener fatigue.
- Genuine OEM Sourcing — Factory-authorized part with full Multiquip traceability, so the specification is exactly what the engineering team intended for these pump assemblies.
A hex bolt of this size plays a critical structural role in concrete pump assemblies, securing major components such as housings, frames, hopper mounts, and drive covers under sustained mechanical stress and vibration. Using a fastener with the correct thread pitch and tensile grade matters because an undersized or mismatched bolt can back out, stretch, or shear under load, leading to misalignment or component separation. Replacing worn or damaged hardware with the correct OEM-spec bolt restores the clamping integrity the pump was built to operate with.
