The Multiquip EM117 Hex Bolt 1/2-13X2 is a genuine OEM replacement fastener designed for the C30HD concrete pump. Sourced directly through Multiquip's authorized parts program, EM117 matches the original hardware specification used on the C30HD at the time of manufacture. If you're servicing or reassembling a C30HD, using the correct OEM bolt ensures proper clamping force and thread engagement throughout the pump assembly.
Key Features
- OEM-Spec Thread Profile — 1/2-13 UNC threading matches the original tapped receivers on the C30HD, ensuring full thread engagement without cross-threading risk.
- Direct-Fit Hardware — Sized at 1/2-13 x 2 inches to drop into the original mounting position without rework or substitution.
- Verified Fitment for C30HD — Confirmed compatibility with the Mayco C30HD concrete pump series.
- Correct Clamping Load — A properly torqued OEM-grade fastener maintains the structural integrity of bolted joints under the continuous vibration and pressure loads generated during concrete pumping operations.
- Genuine Multiquip Part — Carries the full OEM designation, so you know this is the exact hardware called out in the C30HD parts documentation.
Hex bolts like the EM117 are structural fasteners used to clamp and secure major components throughout a concrete pump's frame, hopper, and drive assemblies. Under the constant vibration and cyclic loading of pumping operations, a fastener that is undersized, stretched, or the wrong thread pitch can back out or fail to hold proper tension — leading to loosened assemblies and potential damage to surrounding components. Using the correct OEM bolt ensures the joint is assembled to the original design intent and holds up through repeated service cycles.
