The Multiquip EM105 is a genuine OEM Bolt 1"-14x6" Hex Head designed for the C30HD series concrete pumps, including the C30HD, C30HDNI, C30HDNI Precision, C30HDNI Zenith, C30HDG, C30HDZ, and related Mayco variants. As a factory-sourced fastener, the EM105 meets the original dimensional and grade specifications required for a secure, properly torqued installation. Sourced directly from Multiquip, this bolt ensures the correct thread pitch, length, and head geometry so no field modification is needed to seat it correctly. If you are servicing or rebuilding a C30HD series pump, using the correct OEM fastener is the most straightforward way to restore the assembly to proper specification.
Key Features
- OEM-Grade Fastener Specification — Manufactured to the exact thread class, tensile strength, and dimensional tolerances specified for the C30HD series, ensuring a correct and secure torque hold.
- Exact Thread and Length Match — 1"-14 thread pitch and 6" length match the original bolt exactly, allowing direct installation without re-tapping or shimming.
- Broad C30HD Series Compatibility — Fits C30HD, C30HDNI, C30HDNI Precision, C30HDNI Zenith, C30HDG, and C30HDZ concrete pumps.
- Structural Integrity Under High-Stress Operation — Concrete pumps generate significant hydraulic and mechanical loads; an undersized or incorrect fastener in a critical joint can lead to loosening, misalignment, or component failure during pumping cycles.
- Genuine Multiquip OEM Part — Part number EM105 is a factory-authorized component, ensuring traceability and consistent quality across the C30HD pump lineup.
A hex head bolt of this size plays a structural fastening role in heavy-duty assemblies such as those found in the C30HD series concrete pumps, where components must remain rigidly joined under continuous cyclic pressure and vibration. The 1"-14 fine thread pitch provides superior clamping force retention compared to coarse-thread equivalents, making it well suited to high-load joints that must resist loosening over extended service cycles. When a fastener of this type becomes worn, stretched, or cross-threaded, it compromises the integrity of the assembly it secures, potentially causing misalignment, fluid leaks, or structural failure at the joint.
