The Multiquip EM26426 is a genuine OEM HHC 5/16-18 x 1-3/4 Grade 8 Screw designed for WSHE-A series vibratory truss screeds. As a factory-spec fastener, EM26426 is manufactured to the exact thread pitch, shank length, and tensile grade required by Multiquip engineering — ensuring correct torque retention in vibration-intensive screed applications. This screw is a direct OEM replacement that installs without modification, keeping your truss screed assembly properly secured and structurally sound. Sourced through authorized Multiquip distribution channels, this part carries full OEM quality assurance.
Key Features
- Grade 8 Tensile Strength — High-strength classification resists shear and fastener fatigue under the continuous vibration loads generated by eccentric shaft screed operation.
- Correct Thread Specification — 5/16-18 coarse thread and 1-3/4 inch shank length match the OEM-specified fastener exactly, threading cleanly into existing hardware without reworking the hole pattern.
- Genuine OEM Part — Factory-sourced from Multiquip, this screw meets the same material and dimensional standards as the fastener originally installed on WSHE-A series vibratory screeds.
- Verified WSHE-A Series Fitment — Confirmed for WSHE-A series truss screed assemblies, so you can order with confidence knowing this is the right hardware for your machine.
- Structural Integrity Under Load — A loose or incorrect-grade fastener on a vibrating screed frame can allow truss sections to shift, affecting screeding accuracy and putting stress on surrounding components. The correct Grade 8 rating holds torque through extended operation.
A hex head cap (HHC) screw is a structural fastener used to clamp and secure components within an assembly, relying on its thread engagement and clamping force to hold parts firmly in position. On a vibratory truss screed like the WSHE-A series, fasteners are subjected to constant oscillation, which can work loose or damage under-spec hardware over time. Using the correct Grade 8-rated fastener at the specified thread and length ensures the joint maintains its designed clamping load throughout the screed's service life, preserving frame alignment and overall screeding performance.
