The Multiquip EM513094 is a genuine OEM Bolt 1/2" NC x 1-3/4" designed for Mayco concrete pump models C30HDGA, C30HDG, C30HDN, C30HDNI, and C30HDNI Precision and Zenith variants. As a direct OEM replacement, EM513094 meets the original thread specification and dimensional tolerances required for proper assembly and torque retention on these concrete pump units. Sourced directly through Multiquip's authorized parts network, this bolt ensures a correct fit the first time without the guesswork that comes with generic hardware substitutions.
Key Features
- OEM Thread and Dimensional Accuracy — 1/2" NC (National Coarse) threading and 1-3/4" length match the original Multiquip specification, ensuring proper clamp load and torque values are achievable during assembly.
- Direct Drop-In Replacement — Engineered to install in the same location and orientation as the original hardware, with no reworking of mounting points or mating threads required.
- Broad Mayco Concrete Pump Compatibility — Confirmed fitment across the C30HDGA, C30HDG, C30HDN, C30HDNI, C30HDNI Precision, and C30HDNI Zenith concrete pump models.
- Structural Integrity Under Working Loads — Correct fastener sizing prevents joint loosening or fastener fatigue that can compromise critical pump assembly connections during high-cycle concrete pumping operations.
- Genuine Multiquip OEM Part — Supplied as an authorized OEM component, so the part number, grade, and specification are verified against the original equipment build standard.
A correctly specified fastener is a critical element in any pump assembly — an undersized or incorrect-grade bolt can back out under vibration, strip mating threads, or fail to maintain the clamping force needed to keep pump components properly secured. The Multiquip EM513094 Bolt 1/2" NC x 1-3/4" provides the exact thread form, diameter, and length called out in the original equipment design. When a fastener fails or goes missing on a concrete pump, replacing it with the correct OEM part keeps the assembly torqued to spec and the machine operating as intended.
