Multiquip 124 Bolt 1/2"-13 x 4 G5

The Multiquip 124 Bolt 1/2"-13 x 4 G5 is a genuine OEM fastener covering a broad range of Multiquip, Whiteman, Essick, and Stow concrete mixers, mortar and plaster mixers, masonry saws, and Mayco concrete pumps. As an OEM-sourced component, part 124 is manufactured to the exact thread pitch, grip length, and Grade 5 tensile rating specified for these machines. Correct-specification fasteners matter on high-vibration equipment, and this bolt is the factory-designated hardware for models spanning the MC, WM, EM, CMS, WC, EC, PRO, and C30HD families. Order with confidence knowing this is the same part supplied in original equipment assembly.

Key Features

• Grade 5 Tensile Strength — Rated to Grade 5 standards, delivering the clamping force and shear resistance required on rotating drum assemblies and pump housings that experience continuous vibration loads.
• Correct Thread Specification — 1/2"-13 UNC thread form and 4-inch grip length match the tapped holes in OEM components exactly, so the bolt seats flush and torques to spec without cross-threading or shimming.
• Genuine OEM Part — Sourced directly from Multiquip as part number 124, ensuring the material grade, surface treatment, and dimensional tolerances match original assembly requirements.
• Broad Cross-Equipment Compatibility — A single part number covers MC, WM, EM, CMS, WC, EC, PRO-series mixers, MS-series masonry saws, and C30HD-family Mayco concrete pumps, simplifying parts inventory across a mixed fleet.
• Prevents Structural Loosening — Using an undersized or incorrect-grade fastener on mixer drum supports or pump frames can cause progressive joint movement and component misalignment; the correct Grade 5 bolt maintains clamping integrity over extended service intervals.

A structural hex bolt like the Multiquip 124 serves as the primary threaded fastener holding major assemblies together — drum mounting brackets, gear-housing covers, pump frames, and saw table supports all rely on correctly rated bolts to stay rigid under load and vibration. Grade 5 designation indicates a minimum tensile strength that resists stretching and fatigue cracking in these demanding applications. When a fastener of the wrong grade, thread pitch, or length is substituted, joint preload drops, components shift, and wear accelerates on the mating parts around the fastener — making OEM-spec replacement the practical choice during any scheduled service or repair.
