Multiquip EM492397 Bolt 1/2 x 2-1/2 In.

The Multiquip EM492397 is a genuine OEM Bolt 1/2 x 2-1/2 In. designed for a broad range of Multiquip and Mayco equipment including LS-series concrete pumps, MC-series concrete mixers, and the R2000H roller. As an OEM-sourced fastener, EM492397 is manufactured to the exact dimensions and grade specified by Multiquip, ensuring a correct fit across all compatible units. This bolt is confirmed for use on models including LS600, LS600P, LS500, LS400, LS300, LS300P, LS300G, LS60TD, LS50TD, LS40TD, LS40D, MC94P/S, MC94SK/MC94PK, MC64P/S, MC64SK/MC64PK, MC12PH, EM12M Series, and R2000H. Keeping the correct fastener on hand means faster servicing and confidence that structural joints are secured to spec.

Key Features

• OEM-Grade Fastener Specification — Manufactured to the exact thread pitch, diameter, and tensile grade called out in Multiquip's engineering documentation, so joint integrity is never compromised.
• Direct-Fit Replacement — Matches the original bolt in head size, shank length, and thread form, dropping straight into existing mounting points without rework or modification.
• Wide Fitment Coverage — Verified for LS-series concrete pumps, MC-series concrete mixers, and the R2000H static roller, making it a practical stock item for mixed fleets.
• Structural Reliability — A correctly torqued, properly graded bolt maintains clamping load under the vibration and load cycles typical of concrete pump and mixer operation; an underspec or worn fastener risks joint loosening over time.
• Genuine OEM Sourcing — Supplied as a Multiquip genuine OEM part, meaning the part number EM492397 traces directly back to the manufacturer's parts program for assured authenticity.

A bolt of this size and grade serves as a structural fastener in assemblies that are subject to continuous vibration, load transfer, and mechanical stress — common conditions on concrete pumps, mixers, and rollers. Using the correct fastener grade matters because an undersized or lower-grade bolt may stretch, fatigue, or back out under operating loads, potentially causing component misalignment or failure of the joined assembly. Replacing worn or damaged fasteners with the OEM-specified EM492397 restores the clamping integrity the original design depends on.
