Professional Applications & Engineering Value
This heavy-duty hex head screw in 316 stainless steel addresses critical engineering challenges in corrosive and high-stress environments. The 1"-8 UNC coarse thread configuration delivers superior pull-out resistance in soft materials while enabling rapid assembly in production settings. With 70,000 psi tensile strength and Rockwell B70 hardness, this partially threaded fastener maintains structural integrity under extreme loads, making it ideal for marine equipment, chemical processing plants, and offshore structures. The external hex drive accommodates high-torque applications, while the 9" length provides ample engagement for thick-section assemblies where vibration resistance and long-term reliability are paramount.
Specification Summary & Compliance
Manufactured to ASME B18.2.1 specifications with Class 2A thread fit tolerance for consistent performance. The inch-system fastener features 1"-8 UNC coarse threading with 2 1/2" minimum thread length and partial threading configuration. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance for industrial applications.
