The Multiquip EM130 is a genuine OEM Square Head Bolt 1/2-13x2 1/2 designed for Mayco C30HD and C30HDZ concrete pumps. Sourced directly from Multiquip, this fastener meets the exact material and dimensional specifications required for proper assembly and long-term service in demanding concrete pumping applications. If you're servicing or rebuilding a C30HD or C30HDZ unit, using the correct OEM bolt ensures every connection holds to spec and the pump operates as intended.
Key Features
- OEM-Grade Fastener Material — Manufactured to the same hardness and tensile specification as the original bolt, ensuring proper clamp load and torque retention under the high-vibration conditions of concrete pump operation.
- Exact Dimensional Match — 1/2-13 thread pitch and 2 1/2 inch length match the original hardware exactly, allowing direct installation without thread chasing or modification.
- Square Head Design — The square head profile provides maximum wrench engagement, which is especially valuable when working in tight spaces around pump housing components.
- Confirmed Fitment for Mayco Concrete Pumps — Verified for C30HD and C30HDZ models, so you can order with confidence that EM130 is the correct part for your machine.
- Structural Integrity Where It Counts — A worn, stripped, or incorrect fastener in a concrete pump assembly can lead to misalignment, leaks, or component failure mid-pour; the EM130 keeps critical joints properly secured.
A square head bolt is a structural fastener used to secure major assemblies and housings on concrete pump equipment. The square head format distributes torque force across a broader surface area, making it resistant to rounding under high-load applications and easier to grip with a wrench in confined working areas. When this bolt is missing, damaged, or substituted with an incorrect size, joint integrity is compromised, potentially causing movement or separation of pump components during operation.
