Multiquip EM509562 3/8" NC x 5/8" G5 Bolt

The Multiquip EM509562 is a genuine OEM 3/8" NC x 5/8" G5 Bolt designed for Multiquip hydraulic-driven concrete pump models including the LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD. As a factory-sourced fastener, EM509562 meets the exact grade and dimensional requirements specified for these machines, ensuring a secure, properly torqued connection every time. Sourced directly through Multiquip's OEM parts program and sold by DHS Equipment, this bolt is the correct replacement when servicing or reassembling critical components on your LS-series concrete pump.

Key Features

• Grade 5 Fastener Strength — G5 classification delivers the tensile and shear strength required for structural and mechanical fastening points on hydraulic concrete pump assemblies.
• Exact Thread Specification — 3/8" NC (National Coarse) thread form matches the threaded bores and mating hardware on LS-series pumps without the need for rethreading or adaptation.
• Genuine OEM Part — Factory-sourced under Multiquip part number EM509562, confirming correct length, diameter, thread pitch, and grade for these applications.
• Broad LS-Series Compatibility — Fits LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD hydraulic-driven concrete pumps, covering a wide range of Multiquip's LS pump lineup.
• Corrosion-Resistant Construction — Built to withstand the wet, high-vibration environment typical of concrete pumping operations, helping maintain joint integrity over repeated service cycles.

Fasteners like this 3/8" NC x 5/8" G5 Bolt play a critical role in securing mechanical assemblies, covers, brackets, and hydraulic components on concrete pump equipment. A correctly graded bolt ensures that clamping force is maintained under the vibration and load cycles that concrete pumps experience during operation. Using an undersized or incorrect-grade fastener in these positions can lead to joint loosening, component misalignment, or failure of the secured assembly — making OEM-spec replacement the right choice whenever a fastener is damaged, stripped, or missing.
