The Multiquip EM492371 is a genuine OEM 5/16 NC x 3 Bolt G5 designed for AR13-series asphalt ride-on rollers and LS-series hydraulic-driven concrete pumps, including the AR13D, AR13H, AR13HA/HAR, AR13HC, LS400, LS500, LS40TD, LS50TD, and LS60TD. As a direct Multiquip OEM component, this fastener is manufactured to the same specification as the hardware originally installed at the factory, ensuring correct thread engagement and clamping load. Sourced directly from Multiquip, EM492371 is the correct replacement when the original fastener is damaged, stripped, or lost during service. Verify your model code against the fitment list before ordering to confirm compatibility.
Key Features
- Grade 5 Structural Rating — G5 designation confirms the tensile and shear strength required for load-bearing and structurally critical fastener locations on heavy compaction and pumping equipment.
- Correct Thread Specification — 5/16 NC (National Coarse) thread form matches the tapped holes on AR13 roller and LS-series pump assemblies, seating fully without thread modification.
- Genuine OEM Part — Sourced directly from Multiquip, EM492371 carries the same part number, material grade, and dimensional tolerances as the hardware used in original production builds.
- Broad Model Coverage — A single part number covers AR13D, AR13H, AR13HA/HAR, AR13HC, LS400, LS500, LS40TD, LS50TD, and LS60TD, making it a practical stocking item for fleets running both rollers and concrete pumps.
- Fastener Integrity Under Vibration — Equipment-grade hardware maintains proper clamp load through the sustained vibration and operational stress generated by vibratory rollers and high-cycle concrete pump applications.
A Grade 5 hex bolt provides the structural fastening force that holds critical assemblies together under dynamic load. On vibratory rollers and concrete pumps, fasteners are subjected to continuous vibration, hydraulic pressure cycles, and mechanical stress that can accelerate wear or cause failure if an incorrect or undergrade replacement is used. Installing the correct OEM-specification fastener — with the right thread pitch, length, and tensile rating — ensures joints remain properly torqued and assemblies stay aligned during operation. A stripped, incorrect, or missing fastener in these applications can lead to component loosening, misalignment, or accelerated wear on surrounding parts.
