The Multiquip EM968223 Hex Nut 1/4-28 ST30 60 is a genuine OEM fastener designed for the ST30 swing tube concrete pump. As an authorized Multiquip OEM part, EM968223 is manufactured to the exact thread specification and material grade called out in the original equipment design, ensuring a secure, properly torqued connection every time. This nut is sourced directly through Multiquip's OEM supply chain, so you can trust it meets the same standards as the hardware installed at the factory. If you are servicing an ST30 concrete pump, verifying the correct fastener spec is critical to maintaining structural integrity across the assembly.
Key Features
- Exact Thread Specification — 1/4-28 UNF fine-thread form matches the original fastener spec on the ST30, ensuring full thread engagement without cross-threading risk.
- Genuine OEM Construction — Manufactured to the material grade and dimensional tolerances specified for concrete pump fastener applications, where vibration and hydraulic forces demand consistent clamping strength.
- Direct-Fit Replacement — Drops into the same position as the original hardware with no reworking of mating threads or mounting hardware required.
- Confirmed ST30 Fitment — Validated for the Multiquip ST30 swing tube concrete pump series, eliminating the guesswork of sourcing a generic substitute.
- Vibration Resistance — Fine-thread UNF fasteners provide superior resistance to loosening under the continuous vibration loads typical of concrete pumping operations, helping maintain joint integrity over extended service intervals.
A hex nut is a fundamental fastening component that clamps two or more parts together by threading onto a bolt or stud and resisting rotation under load. On a concrete pump like the ST30, fasteners throughout the frame, hopper, and hydraulic mounting points are subjected to constant vibration and mechanical stress, making correct thread form and material grade essential. Using a mismatched or undersized nut risks fastener loosening, joint separation, or damage to mating threads — all of which can interrupt operation or compromise structural safety on the machine.
