Professional Applications & Engineering Value
Engineered for demanding industrial environments, these 316 stainless steel hex head screws provide critical corrosion resistance where exposure to moisture, chemicals, and salt spray would compromise ordinary fasteners. The UNC coarse thread configuration delivers superior pull-out resistance in softer substrates while maintaining rapid installation speeds. With fully threaded right-hand design and external hex drive, these fasteners achieve maximum clamping force distribution and accommodate high-torque applications without stripping. The combination of Rockwell B70 hardness and 70,000 psi tensile strength ensures structural integrity in heavy machinery, marine equipment, and chemical processing systems where vibration and dynamic loads are constant challenges.
Specification Summary & Compliance
This 3/8"-16 UNC hex head screw features precision Class 2A thread tolerances with coarse thread spacing, manufactured to exact ASME B18.2.1 dimensional standards. The fastener maintains full compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. With dimensions of 3/4" length, 9/16" head width, and 15/64" head height, these screws deliver consistent performance across industrial applications requiring inch system fasteners.
