Professional Applications & Engineering Value

This 3/4"-10 UNC Hex Head Screw is engineered for heavy-duty industrial applications where reliability and corrosion resistance are critical. The 18-8 Stainless Steel material combats rust and chemical exposure in marine, construction, and chemical processing settings. Its partially threaded shank and coarse UNC thread spacing enable quick installation and secure fastening in structural steel, machinery bases, and large equipment assemblies. The external hex drive and substantial 1 1/8" head width provide high torque capability, reducing the risk of stripping during installation. With an 80,000 psi tensile strength and Rockwell B70 hardness, it addresses common failure points in high-vibration environments, ensuring long-term joint integrity and minimizing maintenance downtime.
