Professional Applications & Engineering Value
This 316 stainless steel hex head screw delivers exceptional performance in corrosive and high-stress environments where fastener failure is not an option. The combination of 70,000 psi tensile strength and Rockwell B70 hardness ensures reliable clamping force maintenance under vibration and load variations. The coarse UNC threading (5/8"-11) provides superior resistance to loosening in dynamic applications while enabling rapid assembly in production environments. With its external hex drive and fully threaded design, this fastener solves critical engineering challenges in marine equipment, chemical processing plants, and food processing machinery where both corrosion resistance and structural integrity are paramount requirements.
Specification Summary & Compliance
This hex head screw maintains precise Class 2A thread fit tolerances per UNC standards, ensuring consistent engagement with mating components. Manufactured to ASME B18.2.1 specifications for dimensional accuracy, the fastener features a 15/16" head width and 25/64" head height for optimal wrench engagement. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications with strict chemical substance restrictions.
