Multiquip 492357 Grade 8 Bolt

The Multiquip 492357 Grade 8 Bolt is a genuine OEM fastener designed for a wide range of Multiquip and Whiteman equipment including mixers, concrete pumps, ride-on rollers, walk-behind rollers, and power buggies. As a genuine OEM component sourced directly through the Multiquip parts network, the 492357 delivers the exact tensile strength, thread pitch, and dimensional spec required by the original equipment design. Confirmed fitment includes models WM45HCE, LS300GK, LS300G, LS300P, C30HDGA, C30HDZ, C30HDG, AR13H, AR13HA/HAR, AR13HC, V305EH, V305EK, R2000H, WTB-16, WTB-16PD, WBH-16, WBH-16E, WBH-16EF, WBH-16F, WBH-16EAWD, WBH-16EAWDF, WBH-21EF, WBH-21EFP, WBH21EPA, and LS600. If you are servicing or rebuilding any of these machines, verifying the correct bolt grade and part number before installation is critical to maintaining structural integrity.

Key Features

• High-Tensile Grade 8 Strength — Grade 8 classification means this bolt meets the highest common SAE tensile rating for automotive and equipment fasteners, making it suitable for high-stress structural and mechanical connections.
• Genuine OEM Part — The 492357 is an authentic Multiquip component, manufactured to the exact specifications called out in the original equipment design — not a generic hardware substitute.
• Broad Multi-Equipment Fitment — A single verified part number covering mixers, concrete pumps, asphalt rollers, vibratory rollers, and hydraulic power buggies across multiple Multiquip and Whiteman model lines.
• Drop-In Replacement — Matches the thread form, shank diameter, and head dimensions of the original fastener, allowing direct installation without reworking mounting points or hardware.
• Structural Reliability Under Load — Using the correct grade fastener prevents bolt stretch, shear failure, and loosening under the cyclic loads and vibration these machines generate during operation.
• Critical Safety Fastener — On rotating assemblies, drive systems, and structural frames, an underspec or worn bolt is a direct safety risk. Replacing with the correct Grade 8 OEM part maintains the intended clamping force and joint integrity.

A Grade 8 bolt is a high-strength structural fastener rated for applications that demand resistance to shear, tension, and cyclic stress. On construction equipment like concrete pumps, rollers, mixers, and power buggies, fasteners in drive trains, frames, and rotating assemblies are subject to constant vibration and mechanical load — conditions that will expose any underspec hardware quickly. Using the correct Multiquip 492357 Grade 8 Bolt ensures the joint holds the clamping force the original design depends on. A failed or wrong-grade bolt in these locations can lead to component misalignment, accelerated wear on adjacent parts, or structural failure during operation.
