The Multiquip EM492371 Bolt 5/16 NC x 3 In. G5 is a genuine OEM fastener designed for Multiquip concrete pump and roller equipment, including LS40, LS40TD, LS50TD, LS400, LS500, LS600, LS60TD, AR13H, AR13HA, AR13D, AR13HAR, and VR36HA models. As a genuine OEM component, it meets the exact material and dimensional specifications Multiquip requires in production — no guesswork on thread pitch, length, or grade. This Grade 5 fastener is rated for the structural and mechanical demands of heavy-duty construction equipment, where fastener integrity directly affects the safety and function of critical assemblies.
Key Features
- Grade 5 Tensile Strength — Meets ASTM Grade 5 standards for medium-carbon steel fasteners, providing the tensile and proof load ratings required for structural joints on hydraulic pump and roller equipment.
- Exact Thread Specification — 5/16 NC (National Coarse) thread form and 3-inch length match OEM fastener positions directly, threading into existing tapped holes without re-tapping or modification.
- Genuine OEM Source — Sourced directly through Multiquip, this bolt carries the same part specification used on the original assembly line, ensuring consistent material grade and dimensional accuracy.
- Broad Cross-Model Compatibility — A single part number covering LS-series concrete pumps (LS40, LS50TD, LS400, LS500, LS600) and AR/VR-series rollers (AR13H, AR13HA, VR36HA), making it a practical stock item for mixed fleets.
- Structural Safety Assurance — Using a correctly rated Grade 5 bolt in fastener-critical positions — such as pump housing mounts, roller frame connections, and drive component brackets — helps maintain joint integrity under sustained vibration and load cycling.
A Grade 5 fastener like the EM492371 serves as a structural anchor in assemblies where consistent clamping force is essential — pump housings, roller frames, engine mounts, and drive component brackets all rely on correctly rated bolts to hold alignment and resist loosening under vibration. Substituting an underrated fastener in these positions can lead to joint creep, component misalignment, or fastener failure under load. Using the correct OEM-spec bolt ensures the joint performs to the designed torque and load specifications throughout the service life of the equipment.
