The Multiquip EM505122 is a genuine OEM Hex Bolt 3/4 x 8-1/2 In designed for MG30 series equipment, including MG30T2D, MG30M2D, MG30T3D, MG30M3D, and MG30 models. As a direct OEM replacement, this bolt matches the original specification for thread size, shank length, and grade, ensuring it seats and torques correctly without rework or adaptation. DHS Equipment stocks this part to keep your MG30 fireproofing pump or mixer back in service with confidence. Verify your model number against the fitment list before ordering to confirm compatibility.
Key Features
- OEM-Grade Fastener Integrity — Manufactured to the original thread pitch, shank length, and material grade spec for the MG30 series, so clamping load and torque values stay within design range.
- Exact Dimensional Match — The 3/4 x 8-1/2 In sizing matches the original bolt pattern exactly, allowing the fastener to drop into existing bores and mating hardware without modification.
- Broad MG30 Series Coverage — Confirmed fitment across MG30T2D, MG30M2D, MG30T3D, MG30M3D, and MG30 equipment, covering both fireproofing pump and mixer configurations.
- Structural Connection You Can Trust — A correctly specified bolt at this size maintains joint integrity under the vibration and load cycles these machines generate during continuous operation.
- Critical Torque Retention — Using an undersized or non-OEM fastener in a structural joint risks bolt stretch, thread strip-out, or joint separation — this part eliminates that risk by matching the original hardware specification.
A hex bolt of this size is a structural fastener used to clamp major assemblies or mounting brackets together under significant load. On equipment like the MG30 series fireproofing pumps and mixers, large-diameter bolts hold critical components in alignment during operation, where vibration and mechanical stress are constant. When a bolt of this type is worn, stretched, or replaced with an incorrect grade or length, the joint can lose clamping force, leading to misalignment, accelerated wear on mating components, or fastener failure that takes the machine out of service entirely.
