Professional Applications & Engineering Value
These Grade 5 zinc-plated steel hex head screws deliver critical performance in industrial assembly where vibration resistance and structural integrity are paramount. The combination of UNF fine threading and Class 2A thread fit ensures precise engagement in tapped holes, reducing the risk of cross-threading during installation. The flanged design with serrations provides superior clamping force distribution and prevents rotational loosening in machinery, automotive, and equipment manufacturing applications. With 110,000 psi tensile strength and Rockwell C22 hardness, these fully threaded screws maintain fastener integrity under heavy dynamic loads, making them ideal for structural components, motor mounts, and heavy-duty enclosures where reliability cannot be compromised.
