The Multiquip 492371 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. As a direct Multiquip OEM part, 492371 meets the exact material grade and dimensional specifications required for these machines. This bolt is confirmed to fit the AR13D, AR13H, AR13HA, AR13HAR, AR13HC, LS400, LS500, LS600, LS40TD, LS50TD, and LS60TD. Sourcing the correct grade hardware from the OEM ensures the fastened joint performs as originally engineered, which matters whenever structural or mechanical loads are involved.
Key Features
- Grade 5 Tensile Strength — G5 rating provides the clamping load and shear resistance required for structural and drivetrain fastening points on compaction and pumping equipment.
- Correct Thread Form and Length — 5/16 NC (National Coarse) thread form and 3-inch body length match the OEM hole pattern and engagement depth, so the fastener seats fully without shimming or modification.
- Broad Cross-Family Fitment — Confirmed for AR13D, AR13H, AR13HA, AR13HAR, AR13HC asphalt rollers and LS400, LS500, LS600, LS40TD, LS50TD, LS60TD concrete pumps.
- Prevents Joint Failure — An under-spec or incorrect-length bolt in a load-bearing connection can loosen under vibration or strip threads; replacing with the correct OEM fastener restores the clamping integrity of the joint.
- Genuine Multiquip OEM Hardware — Produced to the same material and finish standards as the original assembly, ensuring consistent torque-to-yield behavior across the service life of the fastener.
A Grade 5 hex bolt is a structural fastener rated for medium-to-high tensile loads, used throughout heavy equipment assemblies to clamp components securely and resist loosening under vibration. The 5/16 NC thread designation means the bolt uses a coarse-pitch thread, which is faster to assemble and more tolerant of debris or minor thread damage than fine-pitch alternatives. When a bolt of this type fails, stretches beyond its yield point, or is substituted with an incorrect grade or length, the joint it holds can shift, fatigue surrounding components, or release entirely — making correct replacement critical on both mobile compaction equipment and high-pressure concrete pump assemblies.
