Professional Applications & Engineering Value

These No. 12 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 action creates secure, vibration-resistant connections without the need for additional locking elements. The A/AB tapping screw type with right-hand threading and fully threaded design ensures maximum engagement in materials up to 0.025" thickness, making them ideal for HVAC systems, electronic enclosures, and automotive assemblies where consistent performance under stress is critical.

Specification Summary & Compliance

These thread forming screws feature a 0.216" thread diameter with 11 TPI precision and Class 2A thread tolerances for consistent performance. The drilled spanner drive (No. 12 size) and standard pan head profile (0.425" diameter, 1/8" height) ensure reliable installation. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, providing assurance of material safety and regulatory acceptance for industrial applications worldwide.
