Professional Applications & Engineering Value

These No. 12 x 4" stainless steel oval head tapping screws are specifically engineered for demanding sheet metal applications where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel composition provides exceptional durability against environmental factors, while the thread forming technology eliminates the need for separate tapping operations, reducing installation time and labor costs. The Phillips No. 3 drive ensures consistent torque application, and the fully threaded design with precise 11 TPI spacing creates secure, vibration-resistant connections in metal fabrication, HVAC systems, and industrial equipment assembly. The oval head profile with standard countersink angle offers both aesthetic appeal and functional flush mounting.

Specification Summary & Compliance

These thread forming tapping screws feature a No. 12 screw size with 0.216" thread diameter and 11 threads per inch, manufactured to standard tolerances for consistent performance. The A/AB tapping screw type with right-hand threading and pointed tip ensures easy starting and reliable engagement in sheet metal applications. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility and suitability for international industrial markets. The 82° countersink angle and standard oval head profile meet industry expectations for professional fastener applications.
