Professional Applications & Engineering Value
These No. 8-15 thread forming tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and permanent fastening are critical. The 18-8 stainless steel composition provides excellent corrosion resistance, making these pan head screws suitable for outdoor equipment, HVAC systems, and industrial machinery exposed to moisture or chemicals. The thread forming technology (Type A/AB) creates strong, clean threads without generating chips, eliminating contamination risks in sensitive assemblies. With their fully threaded design and pointed tip, these screws ensure quick starts and consistent seating depth, reducing installation time while maintaining structural integrity in thin-gauge materials.
Specification Summary & Compliance
These tapping screws feature precise No. 8-15 thread specifications with 0.164" diameter and 15 threads per inch, manufactured to standard tolerances for consistent performance. The square drive (No. 2) ensures positive engagement with installation tools. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and restricted substance adherence. Designed specifically for use with No. 29 drill bits (0.136" diameter), these screws meet industrial standards for thread forming applications in sheet metal up to 0.025" thickness.
