The Multiquip EM968446 Hex Nut 3/4"-10 GR5 is a genuine OEM fastener designed for a wide range of Multiquip concrete pumps, Mayco pumps, and walk-behind rollers including the LS300, LS600, C30HD, and V305EK series. As a direct OEM replacement, EM968446 is manufactured to the same Grade 5 specification as the original hardware, ensuring the correct clamp load and thread engagement for critical fastening points. This hex nut fits an extensive list of models — including the LS300GK, LS300P, LS400, LS500, LS600P, LS50TD, LS40TD, LS40D, LS60TD, C30HDGA, C30HDZ, C30HDG, C30HDNI, V304EY, V304ER, and V304EH — making it a versatile stock item for fleets running multiple Multiquip machine types. Sourcing the exact OEM-specified fastener eliminates guesswork and keeps your equipment operating within its designed tolerances.
Key Features
- Grade 5 Tensile Strength — Rated GR5 for the load-bearing demands of concrete pump and roller assemblies, providing the clamping force these applications require.
- 3/4"-10 UNC Thread Specification — Matches the standard coarse-thread pitch used across multiple Multiquip fastening points, threading on cleanly without chasing or modification.
- Broad Cross-Model Fitment — Compatible with LS300, LS600, C30HD, V305EK, V304EH, V304ER, V304EY, and many additional Multiquip concrete pump and roller models.
- Correct Clamp Load for Structural Joints — Using an undersized or incorrect-grade nut on high-load joints can lead to joint loosening, vibration damage, or structural failure; EM968446 restores the proper clamping specification.
- Genuine OEM Part — Sourced directly from Multiquip, EM968446 carries the same part number referenced in the OEM parts manual, so you know it is the right fastener for the application.
A hex nut is a threaded fastener that mates with a bolt or stud to clamp two or more components together. On concrete pumps and vibratory rollers, hex nuts secure critical structural, hydraulic, and mechanical assemblies that are subject to continuous vibration and heavy dynamic loads. Using a fastener of the correct thread size and grade rating is essential — an incorrect-grade nut can stretch, strip, or back off under load, leading to joint failure, component damage, or unsafe operating conditions. Replacing worn or damaged hardware with the specified Multiquip EM968446 ensures the joint is restored to its original clamping specification.
