• Right-hand threading with 11 threads per inch delivers consistent, reliable engagement in sheet metal substrates

Professional Applications & Engineering Value

These No. 12 thread forming tapping screws are specifically engineered for sheet metal applications where reliability and corrosion resistance are paramount. The 18-8 stainless steel composition provides excellent durability against environmental factors, while the thread forming design eliminates the need for separate tapping operations, reducing assembly time and labor costs. The partially threaded configuration ensures optimal clamping force distribution, preventing material distortion in thin gauge metals. With their one-way drive system and pan head design, these screws offer tamper-resistant security for permanent installations in HVAC systems, electronic enclosures, and industrial equipment where vibration resistance and long-term performance are critical requirements.

Specification Summary & Compliance

These thread forming tapping screws feature a No. 12 size with 0.216" thread diameter and 11 threads per inch in right-hand direction. The screws are designed for use with 3/16" (0.1875") drill bits and accommodate maximum drilling thickness of 0.025". Manufactured to A/AB tapping screw type standards with partial threading and pointed tip for easy starting. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets.
