• Excellent thread-forming capability creates permanent, vibration-resistant threads in sheet metal without chips or debris
• Optimized Phillips drive design provides secure tool engagement and reduces cam-out during installation
• Full threading along entire length ensures maximum holding power and uniform stress distribution
• Precision-engineered pan head profile offers low-profile installation with enhanced bearing surface
• Reliable performance in thin materials with specialized design for 0.025" maximum drilling thickness applications
• Environmental compliance assurance meeting RoHS 3 and REACH standards for industrial safety requirements

Professional Applications & Engineering Value

These No. 12 x 1/2" tapping screws are specifically engineered for sheet metal applications where reliability and corrosion resistance are paramount. The 18-8 stainless steel construction provides exceptional durability against environmental factors, while the thread forming technology (Type A/AB) creates strong, permanent threads in pre-drilled holes without generating metal chips. The Phillips pan head design ensures flush installation with improved torque transmission, making these screws ideal for HVAC systems, electronic enclosures, automotive components, and industrial equipment where vibration resistance and material integrity are critical. The combination of fully threaded construction and precise 0.216" thread diameter with 11 threads per inch delivers superior pull-out strength in thin-gauge materials up to 0.025" thickness.

Specification Summary & Compliance

These thread forming tapping screws feature a No. 12 screw size with 1/2" length, 0.216" thread diameter, and 11 threads per inch configuration. The inch system fasteners maintain precise dimensional accuracy with standard Class 2A thread tolerances. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial compliance. Designed for use with 3/16" (0.1875") drill bits, these screws provide reliable performance in various sheet metal applications while meeting international environmental standards.
