Professional Applications & Engineering Value

These 6-32 x 1/2" zinc-plated steel tapping screws deliver exceptional engineering value by solving critical fastening challenges in metalworking and fabrication. The Type F thread cutting design with UNC coarse spacing eliminates the need for separate tapping operations, significantly reducing assembly time in aluminum, brass, cast iron, and sheet metal applications. The zinc-plated steel construction provides durable corrosion protection, while the Phillips pan head with standard rounded profile ensures easy installation with common tools. These thread cutting screws create their own mating threads in base materials, providing secure, vibration-resistant connections ideal for industrial fasteners in construction, machinery, and equipment manufacturing where reliability is paramount.

Specification Summary & Compliance

This tapping screw features precise 6-32 UNC thread with coarse spacing and right-hand direction, manufactured to ASME B18.6.3 specifications (SAE J933) ensuring dimensional accuracy and performance reliability. The fastener is fully threaded with a blunt tip and round shank cross-section, designed for use with No. 31 drill bit (0.12" diameter). Compliance with RoHS 3 (2015/863/EU) standards ensures environmental responsibility and suitability for regulated industries worldwide.
