Professional Applications & Engineering Value

These No. 8 Phillips flat head tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming design eliminates the need for tapping operations while creating stronger threads through material displacement rather than cutting. The Black-Oxide Steel construction provides reliable corrosion protection in industrial environments, while the 82° countersink angle ensures proper seating in standard sheet metal applications. The combination of fully threaded design and pointed tip facilitates quick starts and maximum thread engagement, significantly reducing installation time in high-volume manufacturing operations. These A/AB type tapping screws are engineered to withstand the rigors of metalworking applications while maintaining consistent performance across production runs.

Specification Summary & Compliance

These thread forming screws feature precise dimensional specifications including 0.164" thread diameter, 15 threads per inch, and 1/2" length with Class 2A thread tolerances. The flat head design incorporates standard profile with 0.262" head diameter and 0.083" head height. Manufactured to industry standards for sheet metal fasteners, these screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial compliance. The specified No. 29 drill bit (0.136") diameter and 0.025" maximum drilling thickness provide clear installation guidelines for optimal performance in metal assembly applications.
