Professional Applications & Engineering Value
This 316 stainless steel socket head cap screw delivers critical performance advantages in demanding industrial applications where corrosion resistance and mechanical reliability are paramount. The combination of UNC coarse threading and Class 3A thread fit provides excellent engagement in both through-holes and tapped holes, reducing installation time while maintaining precision alignment. The passivated finish significantly enhances the natural corrosion resistance of 316 stainless steel, making these fasteners ideal for chemical processing equipment, marine hardware, and food processing machinery where exposure to aggressive media is common. The partially threaded design offers engineering flexibility, allowing the unthreaded shoulder to function as a precision dowel while the threaded portion provides secure clamping force.
Specification Summary & Compliance
This socket head cap screw features 7/8"-9 UNC coarse threads with Class 3A thread fit for precision assembly applications. Manufacturing specifications include Rockwell B70 hardness and 70,000 psi tensile strength. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance across global markets.
