Multiquip EM124 Tornillo 1/2"-13 x 4 G5

The Multiquip EM124 Tornillo 1/2"-13 x 4 G5 is a genuine OEM bolt designed for a wide range of Multiquip, Whiteman, and Essick concrete and mortar mixers as well as Mayco C30HD series concrete pumps. As a direct OEM replacement, the EM124 meets the original design requirements for thread pitch, grip length, and Grade 5 tensile strength — keeping critical assemblies fastened and secure under continuous operating loads. Confirmed fitment includes MC94, MC64, MC44, WM90, WM70, WM63, EM90, EM70, EM12M series, and C30HD family models. Sourced directly through authorized Multiquip distribution, this bolt ships as the exact component specified for these machines.

Key Features

• Grade 5 Tensile Strength — SAE Grade 5 rating delivers the clamping force and shear resistance required for structural and drivetrain fastener positions on mixer and pump assemblies.
• Correct Thread Specification — 1/2"-13 UNC thread form and 4-inch grip length match the original fastener specification, threading directly into existing tapped holes without rework.
• Broad Mixer and Pump Fitment — Compatible with MC94, MC64, MC44, WM90, WM70, WM63, EM90, EM70, EM12M series mixers and C30HD, C30HDNI, C30HDG, and C30HDZ concrete pump models.
• Genuine OEM Part — Supplied as an authentic Multiquip component, ensuring the bolt geometry, material grade, and finish match what was installed at the factory on each covered model.
• Maintains Structural Integrity — Using the correct grade and length fastener prevents joint movement, housing misalignment, and accelerated wear on surrounding components that an undersized or incorrect bolt would allow.

A fastener bolt in a mixer or concrete pump serves as the primary mechanical connection holding housings, guards, drum supports, and drive components together under sustained vibration and load. When a bolt of incorrect grade or length is used, the joint can stretch, loosen, or fail — leading to component movement that accelerates wear on adjacent parts and can create unsafe operating conditions. The Multiquip EM124 provides the specified Grade 5 clamping force and thread engagement needed to keep these assemblies stable and functioning as designed throughout the service life of the machine.
