Professional Applications & Engineering Value

These 316 stainless steel tapping screws are engineered specifically for sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming technology (A/AB type) eliminates the need for separate tapping operations, reducing assembly time and labor costs while creating stronger, more reliable threads that resist vibration loosening. The fully threaded design ensures maximum engagement in materials up to 0.025" thickness, providing superior pull-out resistance in HVAC systems, electronic enclosures, and industrial equipment. The combination of Phillips drive and oval head profile offers both installation efficiency and a professional finished appearance, making these fasteners ideal for applications where both performance and aesthetics matter in demanding environments.

Specification Summary & Compliance

This No. 12 x 1" tapping screw features precision right-hand threads with 0.216" diameter and 11 threads per inch, manufactured to industry standards for thread forming applications. The fastener includes a standard oval head with 0.412" diameter and is designed for use with 3/16" drill bits. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and meets international industrial requirements for hazardous substance restrictions.
