Zeron 100 FG studs are super duplex stainless steel continuous-thread studs (UNS S32760) cut from FG cold-drawn rod per ASTM A1082 + ASME B1.1. FG yield matches A193 B7 envelope. Use for high-load tie-rods, high-torque anchor studs, and through-bolted joints where SA yield is insufficient. For ASME B16.5 flange double-end stud bolts see FG stud bolts.
