The Multiquip EM133 is a genuine OEM Bolt 1"-14x2" Hex Head designed for C30HD series concrete pumps, including the C30HD, C30HDNI, C30HDNI Precision, C30HDNI Zenith, C30HDG, and C30HDZ models. As a factory-sourced fastener, EM133 matches the exact thread pitch, grade, and dimensional spec of the original hardware used in Multiquip Mayco concrete pump assembly. This bolt is a direct-fit replacement that installs without modification, ensuring proper torque retention and structural integrity across the pump assembly. Sourcing the correct OEM fastener matters on high-cycle concrete pump equipment where incorrect hardware can compromise joint clamping force and lead to premature failure.
Key Features
- Correct Thread Specification: — 1"-14 thread pitch matches the original fastener spec used in C30HD series pump assembly, ensuring full thread engagement and proper clamping load.
- Genuine OEM Hardware: — Factory-sourced from Multiquip, this bolt meets the same material grade and dimensional tolerances as the hardware originally installed on Mayco concrete pumps.
- Broad C30HD Series Fitment: — Compatible with C30HD, C30HDNI, C30HDNI Precision, C30HDNI Zenith, C30HDG, and C30HDZ concrete pump models.
- Structural Reliability Under Load: — Concrete pumps operate under sustained hydraulic and mechanical stress; using a correctly rated bolt maintains joint integrity and prevents loosening or fastener fatigue over time.
- Exact Part Number Reference: — Order with confidence using Multiquip part number EM133 to ensure you receive the correct bolt for your specific machine configuration.
A hex head bolt like the EM133 serves as a primary structural fastener within the concrete pump assembly, holding critical components together under the continuous vibration, pressure, and mechanical stress that concrete pumping generates. Using a bolt with the correct thread pitch, length, and material grade ensures the joint maintains its clamping force through repeated pump cycles. When a fastener is worn, cross-threaded, or replaced with an incorrect substitute, the resulting loss of clamping force can allow joint movement, cause accelerated wear on mating components, and in severe cases lead to component separation during operation.
