The Multiquip EM492365 Bolt 5/16" 1x1-1/4" Grade 5 is a genuine OEM fastener designed for AR13H and AR13HA/HAR asphalt ride-on rollers, WTB-16 and WBH-16 series Whiteman power buggies, and EM900SD Essick mixers. As a factory-sourced component, EM492365 meets the exact material grade and dimensional tolerances specified by Multiquip for these applications. Grade 5 construction delivers the tensile strength required to hold up under the vibration and load cycles common to compaction and material-handling equipment. DHS Equipment supplies this part as a direct OEM replacement so you can restore your machine with confidence.
Key Features
- Grade 5 Tensile Strength — Medium-carbon steel Grade 5 rating provides the clamping force and shear resistance needed on high-vibration equipment like rollers and power buggies.
- Genuine OEM Specification — Sourced directly from Multiquip, this bolt matches the exact thread pitch, head size, and length called out in the OEM parts documentation for these models.
- Broad Fitment Across Multiquip Families — Confirmed for AR13H, AR13HA/HAR, and AR13HC rollers; WTB-16, WBH-16, WBH-16E, WBH-16EF, WBH-16EAWD, WBH-16EAWDF, and WBH21EPA power buggies; and EM900SD mixers.
- Maintains Structural Integrity — A correct-spec fastener keeps assemblies torqued to designed clamping loads, preventing loosening, wear acceleration, and potential structural failure during operation.
- Direct Drop-In Replacement — Identical head drive type, shank diameter, and thread form allow installation with standard hand tools and no reworking of mating components.
A Grade 5 bolt is a medium-carbon steel fastener heat-treated to achieve a minimum tensile strength of 120,000 psi, making it suitable for structural and mechanical connections that experience dynamic loading and vibration. On equipment like rollers, power buggies, and mixers, fasteners are subjected to continuous stress from engine vibration, ground impact, and drivetrain torque — conditions that can cause under-spec bolts to stretch, loosen, or fail prematurely. Using the correct OEM-grade fastener ensures joints maintain their designed clamping load throughout the service interval, protecting surrounding components from the wear and misalignment that a loose or failed bolt can cause.
