Multiquip EM963102 Bolt 1/2 x 1-1/4 In

The Multiquip EM963102 is a genuine OEM Bolt 1/2 x 1-1/4 In designed for a wide range of Multiquip, Mayco, Whiteman, and Essick equipment across multiple machine families. This fastener is confirmed compatible with LS-series concrete pumps including the LS50TD, LS40TD, LS40D, LS400, LS500, LS600, and LS300 variants, V3-series walk-behind rollers such as the V303E, V304EH, V304ER, V304EY, and V305EK, Whiteman and Essick plaster and mortar mixers including the WM70SLF, WM70PLF, WM90SLF, WM90PLF, EM70SLF, and EM90SLF, PRO12-series stationary mixers, and MQ600H-series trash pumps. As a genuine OEM part sourced directly from Multiquip, EM963102 meets the exact dimensions and grade specifications called for in the original equipment build.

Key Features

• Correct Grade and Dimension — Manufactured to the exact 1/2 x 1-1/4 in. specification required by Multiquip engineering, ensuring proper clamping load and thread engagement across all listed assemblies.
• Genuine OEM Quality — Produced to the same material and hardness standard as the original fastener, so structural integrity is maintained under operating vibration and load cycles.
• Broad Cross-Family Fitment — A single part number covers LS-series concrete pumps (LS50TD, LS40TD, LS300GK, LS600), V3-series rollers (V303E, V305EK), WM and EM mortar mixers, PRO12 stationary mixers, and MQ600H-series trash pumps.
• Direct Drop-In Replacement — Threads, head size, and shank length match the original bolt exactly, so reassembly proceeds without reworking mating components or hardware.
• Prevents Fastener-Related Failures — A worn, stretched, or incorrect bolt can allow joint movement that accelerates wear on surrounding components; replacing with EM963102 restores the designed clamping force.

A structural bolt is one of the most fundamental fasteners in any piece of heavy equipment, transferring load between joined components and keeping assemblies rigid under continuous vibration and mechanical stress. The Multiquip EM963102 Bolt 1/2 x 1-1/4 In serves this role across diverse machine types — from concrete pump frames and roller chassis to mixer housings and pump bodies. When a bolt stretches, corrodes, or is replaced with an incorrect size, the resulting joint looseness can cause accelerated wear on mating parts, misalignment, and in load-bearing applications, structural failure of the fastened joint. Using the correct OEM-specified fastener ensures the joint performs as designed for the service life of the surrounding assembly.
