• 410 stainless steel construction provides excellent corrosion resistance and durability for long-lasting performance in demanding industrial environments
• Thread forming technology creates stronger, more secure connections with superior holding power compared to conventional fastening methods
• Phillips No. 3 drive system ensures efficient torque transfer and reduces cam-out during installation for consistent, reliable fastening
• 0.21" maximum drilling thickness handles substantial material depths, making these screws versatile for various metal fabrication projects
• Fully threaded design maximizes grip length and distributes stress evenly along the entire fastener for enhanced joint integrity
• Pan head configuration offers a low-profile finish while providing adequate bearing surface for secure fastening in metal assemblies

Professional Applications & Engineering Value

These No. 12 self-drilling tapping screws are engineered to address critical challenges in metal fabrication and construction applications. The 410 stainless steel composition delivers reliable corrosion resistance, while the specialized drill tip design penetrates materials up to 0.21" thick without pilot holes, significantly reducing installation time and labor costs. The thread forming BSD technology creates precise mating threads in steel, stainless steel, and sheet metal substrates, resulting in superior pull-out resistance and vibration-proof connections. The Phillips drive system ensures efficient power transfer during installation, making these fasteners ideal for HVAC systems, metal building construction, industrial equipment assembly, and automotive applications where reliability and speed of installation are paramount.

Specification Summary & Compliance

These self-drilling tapping screws feature a No. 12 screw size with 0.216" thread diameter and 14 threads per inch, manufactured to BSD (British Standard Drilling) specifications. The fully threaded design maintains consistent Class 2A thread tolerances for reliable engagement, while the pan head configuration with Phillips No. 3 drive ensures compatibility with standard industrial tools. These fasteners comply with industry standards for thread forming screws and are manufactured using 410 stainless steel that meets relevant material specifications for industrial fastening applications.
