Professional Applications & Engineering Value
This 316 stainless steel hex head screw delivers critical performance where corrosion resistance and structural integrity are paramount. The combination of UNC coarse threading and Class 2A thread fit ensures rapid assembly in industrial equipment, marine hardware, and chemical processing systems where exposure to corrosive elements would compromise ordinary fasteners. The fully threaded 6-inch length provides consistent clamping force across extended joints, while the external hex drive accommodates high-torque applications. Engineered to withstand aggressive environments including saltwater, chemicals, and extreme temperatures, these hex head screws maintain their mechanical properties and 70,000 PSI tensile strength where inferior fasteners would fail prematurely.
Specification Summary & Compliance
This inch-system fastener features 5/16"-18 UNC coarse threads with Class 2A tolerance for reliable fitment. Manufactured to ASME B18.2.1 specifications with complete compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. The right-hand thread direction and fully threaded design ensure consistent performance across the entire 6-inch length with maintained Rockwell B70 hardness and mechanical properties.
