Professional Applications & Engineering Value

These 316 stainless steel thread forming screws solve critical challenges in sheet metal fabrication and assembly. The A/AB tapping screw type with thread forming method creates strong, strip-resistant threads in ductile metals without chip formation, eliminating cleanup and ensuring reliable connections. The fully threaded design with pointed tip enables quick starts in pre-drilled No. 32 holes (0.116" diameter), while the pan head with square drive prevents cam-out during high-torque installation. Ideal for industrial equipment, marine components, and chemical processing applications where corrosion resistance and vibration durability are essential.
