Professional Applications & Engineering Value

This 316 stainless steel hex head screw delivers exceptional engineering value in corrosive environments where fastener failure is not an option. The 3/8"-16 UNC coarse thread configuration ensures rapid installation while maintaining structural integrity in applications ranging from marine equipment to chemical processing systems. With 70,000 psi tensile strength and Rockwell B70 hardness, this fastener withstands vibration, thermal cycling, and mechanical stress that would compromise inferior fasteners. The external hex drive provides positive engagement with standard tools, reducing installation time and preventing tool slippage. Partially threaded design concentrates clamping force precisely where needed, making it ideal for structural assemblies requiring controlled joint compression in industrial machinery, offshore platforms, and wastewater treatment facilities.
