Multiquip EM512185 HHC Screw 1/4-20 x 1-3/4

The Multiquip EM512185 HHC Screw 1/4-20 x 1-3/4 is a genuine OEM fastener designed for a wide range of Multiquip equipment including AR14H rollers, WBH-16, WBH-16E, WBH-16F, WBH-16EF, WBH-16EAWD, WBH-16EAWDF, WBH-21EF, WBH-21EFP, WBH21EPA, and WPB16 power buggies, LS600, LS600P, and LS60TD concrete pumps, MG30, MG30T2D, MG30M2D, MG30T3D, and MG30M3D fireproofing pumps and mixers. As a genuine Multiquip OEM part, EM512185 is manufactured to the exact thread pitch, shank length, and head specification required for proper assembly across all listed equipment families. Sourcing the correct fastener grade and dimension is critical — an incorrect screw can lead to loose assemblies, component misalignment, or premature mechanical failure. DHS Equipment stocks this part to keep your Multiquip machines running with the hardware they were built with.

Key Features

• Correct Thread Specification — 1/4-20 UNC thread pitch and 1-3/4 inch shank length match the original fastener specification exactly, ensuring proper thread engagement without stripping or bottoming out.
• Hex Head Cap Construction — The hex head cap (HHC) profile allows standard wrench or socket installation, consistent with the fastener style used throughout Multiquip assemblies.
• Genuine OEM Part — Produced under Multiquip's OEM program to ensure the correct material grade and dimensional tolerances for secure, lasting fastener performance across all covered equipment families.
• Broad Equipment Compatibility — A single part number covers multiple Multiquip product families including AR14H rollers, WBH and WPB series power buggies, LS600 series concrete pumps, and MG30 series fireproofing and mixing units.
• Structural Integrity Where It Counts — A correctly torqued, properly graded fastener maintains tight tolerances in panels, guards, and structural assemblies — preventing vibration-induced loosening during operation.

A hex head cap screw is a standard structural fastener used throughout heavy equipment assemblies to securely join components such as housings, guards, brackets, and frames. The 1/4-20 designation refers to the screw's nominal diameter of 1/4 inch and a thread pitch of 20 threads per inch, while the 1-3/4 inch length determines how deep the fastener engages into the mating material. When a fastener of the wrong thread pitch, length, or grade is used, it can fail to achieve proper clamp load, back out under vibration, or damage the receiving threads — any of which can compromise the integrity of the assembly it secures. Using the correct OEM-specified fastener like the part ensures proper torque retention and long-term joint stability across the equipment families it serves.
