Multiquip EM16524 Screw HHC 1/2-13 x 1-1/4

The Multiquip EM16524 is a genuine OEM Screw HHC 1/2-13 x 1-1/4 sourced directly from Multiquip and used across a wide range of equipment families including Whiteman power buggies, hydraulic-driven concrete pumps, pavement saws, roller screeds, and more. As an OEM-sourced fastener, EM16524 is manufactured to the exact thread pitch, head dimensions, and material specification required by Multiquip for these applications. Fitment spans models including WBH-16, WBH-16E, WBH-16EAWD, WBH-21EF, WTB-16, LS40, LS40TD, LS50TD, LS400, LS450, LS500, LS600, SP303516, SP303520, SP303526, SP303530, WRS5200, and additional Multiquip equipment families. Using the correct OEM fastener eliminates the risk of mismatched thread engagement or incorrect clamping force that can result from substituting non-specified hardware.

Key Features

• Genuine OEM Thread Specification — 1/2-13 UNC thread form and 1-1/4 inch length match Multiquip's original design intent, ensuring full thread engagement at every fastened joint.
• Hex Head Cap Design — The hex head cap (HHC) profile seats correctly against Multiquip-specified hardware interfaces without shim or adapter.
• Broad Cross-Family Fitment — A single part number covering WBH and WTB power buggies, LS-series concrete pumps, SP-series pavement saws, WRS roller screeds, and select generator and pump models keeps your parts inventory lean.
• Correct Clamping Load — OEM-grade material ensures the fastener reaches and holds the specified torque value, maintaining structural integrity at joints subject to vibration and load cycling.
• Direct Replacement — this part installs in place of the original fastener with no reworking of mating holes or hardware, keeping maintenance straightforward for field technicians.

A hex head cap screw is a structural fastener used to clamp two or more components together at a threaded connection point. The 1/2-13 designation refers to a half-inch nominal diameter with 13 threads per inch, a coarse-thread standard that provides strong clamping force and resistance to loosening under vibration — conditions common across compaction, pumping, and cutting equipment. When a fastener of this type is worn, stretched, or incorrectly specified, joint integrity can be compromised, leading to component movement, accelerated wear at mating surfaces, or structural failure during operation. Replacing a damaged or missing screw with the correct OEM part number restores the fastened joint to its engineered specification.
