S-90087A101 2-56 x 3/16" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Excellent thread-cutting performance in aluminum, brass, cast iron, and sheet metal without requiring pre-tapped holes
• Enhanced driving efficiency with Phillips No. 1 drive design that reduces cam-out and improves installation control
• Maximum material engagement through fully threaded shank design that provides superior holding power across the entire fastener length
• Reliable fastening in various materials with UNC coarse thread spacing that ensures secure connections in soft metals and sheet applications
• Industry-standard compliance meeting ASME B18.6.3 specifications for consistent quality and dimensional accuracy
• Environmental regulation adherence with RoHS 3 compliance for use in regulated industries and international markets

Professional Applications & Engineering Value

These 2-56 UNC tapping screws deliver exceptional engineering value in metal fabrication and assembly operations. The zinc-plated steel construction provides essential corrosion protection while maintaining the strength required for demanding applications. The Type F thread cutting design with blunt tip and coarse UNC thread spacing enables efficient installation in aluminum, brass, cast iron, and sheet metal without tap preparation, significantly reducing assembly time and labor costs. The Phillips drive system ensures reliable torque transmission during installation, while the fully threaded configuration maximizes pull-out resistance. These self-tapping screws are engineered to solve common fastening challenges in electrical enclosures, machinery components, and metal framework assemblies where vibration resistance and long-term reliability are critical.
