Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional performance in sheet metal fabrication and assembly operations. The A/AB thread forming technology eliminates the need for pre-tapped holes, creating strong, permanent threads in materials up to 0.025" thickness. The Phillips pan head design with rounded profile provides a flush finish while the fully threaded No. 12 screw ensures maximum pull-out resistance. Engineered for use with standard 3/16" drill bits, these industrial fasteners significantly reduce installation time and labor costs while maintaining consistent clamping force in HVAC systems, electrical enclosures, and automotive components where vibration resistance is critical.

Specification Summary & Compliance

This No. 12 x 1-3/4" tapping screw features precision 0.216" thread diameter with 11 threads per inch and standard thread tolerances. The screw meets industry standards for thread forming applications in sheet metal with specified 3/16" (0.1875") drill bit compatibility. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. The zinc-plated steel construction provides reliable corrosion protection while maintaining the mechanical strength required for demanding fastening applications.
