Professional Applications & Engineering Value

Engineered for demanding industrial environments, these 316 stainless steel hex head screws deliver exceptional performance where corrosion resistance and structural integrity are paramount. The coarse UNC threading provides superior engagement in softer materials and faster installation times, while the partial threading design offers optimal stress distribution across joint interfaces. With their external hex drive configuration, these fasteners enable high-torque applications common in structural steelwork, marine equipment, and chemical processing installations. The combination of 70,000 psi tensile strength and Rockwell B70 hardness ensures reliable performance under sustained mechanical loads, making them ideal for critical connections in infrastructure, heavy machinery, and offshore applications where failure is not an option.

Specification Summary & Compliance

These hex head screws feature precise Class 2A thread fit tolerances with 7/8"-9 UNC coarse threading in accordance with ASME B18.2.1 manufacturing standards. The 9-inch length with 2 1/4-inch minimum thread length provides consistent dimensional accuracy. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and workplace safety standards are met throughout the product lifecycle.
