The Multiquip EM26426 HHC Screw 5/16-18 x 1-3/4 Grade 8 is a genuine OEM fastener designed for WSHE-A series vibratory truss screeds. As a direct OEM replacement, this screw is manufactured to the exact thread pitch, length, and tensile specification called out in the original Multiquip bill of materials — no guesswork on fitment or grade. Sourced directly through authorized Multiquip supply channels, EM26426 is the correct hardware choice for technicians and operators maintaining WSHE-A screed assemblies. DHS Equipment stocks genuine Multiquip OEM parts so you can get the right component without delay.
Key Features
- Grade 8 Tensile Strength — High-strength Grade 8 classification delivers the clamping force and vibration resistance demanded by screed applications subject to continuous oscillation.
- Correct Thread Specification — 5/16-18 UNC thread form and 1-3/4-inch length match the original fastener exactly, threading into existing hardware points without rework.
- Hex Head Cap (HHC) Configuration — Standard hex head cap profile allows installation with common hand and impact tools already on the jobsite.
- WSHE-A Series Fitment — Confirmed OEM application for Multiquip WSHE-A vibratory truss screed models, eliminating compatibility uncertainty during assembly or field repair.
- Genuine OEM Hardware — Sourced from Multiquip's authorized parts network, this fastener meets the same material and dimensional standards as the original production component.
Hex head cap screws like the EM26426 serve as structural fasteners that clamp and secure critical assemblies on vibratory truss screeds, including truss sections, engine mounts, and bracket connections that must remain tight under sustained vibration. Grade 8 hardware is specified in these applications because its elevated proof load resists loosening and fatigue cracking far better than standard Grade 5 or ungraded fasteners. When the wrong grade or thread spec is used, fasteners can back out or fail under load, compromising the structural integrity of the screed assembly and affecting the quality of the finished concrete surface.
