Professional Applications & Engineering Value
These zinc-plated steel tapping screws deliver exceptional engineering value by eliminating the need for pre-tapped holes in aluminum, brass, cast iron, and sheet metal applications. The Type F thread cutting design with UNC coarse threads creates precise mating threads during installation, significantly reducing assembly time and labor costs. The fully threaded blunt-tip configuration ensures maximum thread engagement while the Phillips drive system provides reliable torque transmission without specialized tools. Ideal for industrial construction and manufacturing environments, these screws maintain structural integrity in vibration-prone applications where thread cutting screws prevent loosening and maintain clamp load over extended service periods.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications (SAE J933) with UNC 8-32 thread size, 5/8" length, and standard dimensional tolerances. Features zinc-plated steel construction with pan head style, Phillips No. 2 drive, and fully threaded blunt-tip design. Compatible with No. 26 drill bit (0.147" diameter) for proper hole preparation. Compliant with RoHS 3 (2015/863/EU) environmental regulations, ensuring safe use in various industrial and commercial applications.
