Professional Applications & Engineering Value
These 3/8"-16 UNC tapping screws deliver exceptional engineering value in demanding industrial applications. The Type F thread cutting design with blunt tip and coarse UNC thread spacing creates precise, durable threads in various materials including aluminum, brass, cast iron, and sheet metal. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength. The Phillips No. 4 drive style ensures efficient installation with standard tools, reducing assembly time and labor costs. These self-tapping screws eliminate the need for separate tapping operations, making them ideal for high-volume manufacturing and maintenance applications where reliability and speed are critical.
Specification Summary & Compliance
These tapping screws feature precise 3/8"-16 UNC coarse threads with full threading along the 3" length. The flat head design incorporates standard profile with 82° countersink angle for flush mounting. Manufacturing specifications comply with ASME B18.6.3 standards (SAE J933), ensuring dimensional accuracy and performance reliability. Environmental compliance includes RoHS 3 (2015/863/EU) certification, confirming adherence to hazardous substance restrictions. Recommended drill bit size T (0.358" diameter) ensures proper hole preparation for optimal thread engagement and holding strength.
