Professional Applications & Engineering Value
These No. 12 tapping screws deliver exceptional value in metal fabrication and construction applications. The 410 Stainless Steel composition provides excellent corrosion resistance while maintaining high strength, making them perfect for outdoor structures, HVAC systems, and industrial equipment. The thread forming technology creates precise, tight-fitting threads that resist loosening under vibration, a common challenge in machinery and automotive assemblies. With their self-drilling capability and BSD tapping screw design, they significantly reduce installation time in steel, stainless steel, and sheet metal applications by eliminating separate drilling operations. The combination of fully threaded design and right-hand thread configuration ensures maximum pull-out strength and reliable performance in demanding industrial environments.
Specification Summary & Compliance
This thread forming screw features precision No. 12 size with 14 threads per inch and 1-1/4" length. The pan head design incorporates a square drive (No. 3) for secure installation. Manufactured to BSD tapping screw standards with fully threaded configuration and No. 3 drill tip capable of penetrating up to 0.187" thickness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for environmental safety and industrial use.
