Professional Applications & Engineering Value
These No. 12 self-drilling tapping screws deliver exceptional value in sheet metal and aluminum fabrication by eliminating multiple operational steps. The 18-8 stainless steel composition provides outstanding corrosion resistance in harsh environments, while the thread forming design creates durable, vibration-resistant connections without requiring pre-tapped holes. The integrated No. 3 drill tip efficiently penetrates materials up to 0.21" thick, significantly reducing installation time and labor costs. The square drive system ensures maximum torque transfer without stripping, making these industrial fasteners ideal for high-volume production environments where reliability and efficiency are critical.
Specification Summary & Compliance
These self-drilling tapping screws feature precise dimensional specifications including 0.216" thread diameter, 14 threads per inch, and 1-1/4" length with fully threaded design. The pan head configuration measures 0.425" diameter with 0.151" height, providing optimal bearing surface. Manufactured to industry standards for thread forming screws with right-hand threading direction and round shank cross-section. The 18-8 stainless steel composition ensures compliance with corrosion resistance requirements for industrial applications.
