Key Features

• Grade 5 Structural Integrity — GRD5 designation confirms this bolt meets the tensile and shear strength requirements for load-bearing fastener positions on mixer and pump assemblies.
• Exact Thread Specification — 1" NFX2" thread profile matches the tapped receivers on compatible Essick mixer and Mayco pump housings without reworking or chasing threads.
• Genuine OEM Component — Manufactured to Multiquip's original design spec, so dimensions, grade, and finish are consistent with what left the factory.
• Broad Fitment Across Two Equipment Families — Confirmed for PRO12, PRO12E51, PRO12E53, and PRO20 Essick stationary mixers, plus the C30HDGA Mayco concrete pump.
• Critical Connection Point — A correctly torqued, properly graded bolt holds structural assemblies in alignment under continuous vibration; a worn or incorrect fastener can allow movement that damages surrounding components.

A Grade 5 bolt like the Multiquip 502125 is a structural fastener rated for higher tensile loads than standard hardware-grade bolts, making it the specified choice for heavy-duty equipment assemblies that operate under sustained mechanical stress and vibration. On stationary mixers and concrete pumps, fasteners at key joint locations hold drive components, drum mounts, and pump housings in precise alignment during operation. When a bolt of incorrect grade or thread pitch is used as a substitute, it can stretch, strip, or loosen under load, leading to misalignment, accelerated wear on surrounding parts, or loss of structural integrity in the assembly.
