S-94060A560 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with self-drilling tip that penetrates up to 0.22" thickness in steel and sheet metal
• Superior corrosion resistance through zinc-plated steel construction for extended service life in industrial environments
• Enhanced driving efficiency with No. 3 Phillips drive that reduces cam-out and improves installation speed
• Maximum holding power achieved through fully threaded design that maintains consistent grip along the entire 2 1/2" length
• Reliable thread formation via BSD thread forming design that creates strong, secure fastenings in metal substrates
• Optimized for industrial applications with 1/4"-14 thread specification designed for demanding steel and sheet metal fastening
• Environmental compliance assurance with RoHS 3 certification for safe, regulated manufacturing standards

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional engineering value by solving critical installation challenges in metal fabrication and construction. The integrated self-drilling tip (No. 3 drill type) eliminates the time-consuming two-step process of drilling and tapping, significantly reducing labor costs while maintaining precision in steel and sheet metal applications. The thread forming design creates stronger thread engagement than cutting alternatives, as it work-hardens the surrounding material rather than removing it. Combined with the Phillips drive system and fully threaded configuration, these BSD tapping screws provide reliable, vibration-resistant fastenings that withstand industrial stresses while the zinc plating offers essential corrosion protection for long-term performance in demanding environments.

Specification Summary & Compliance

These 1/4"-14 tapping screws feature standard inch measurements with right-hand threading and approximately 14 threads per inch. The zinc-plated steel construction meets industrial strength requirements while the BSD thread forming method ensures consistent performance. Manufacturing complies with RoHS 3 (2015/863/EU) environmental regulations, confirming the absence of restricted hazardous substances. The screws are engineered for precision installation in steel and sheet metal up to 0.22" thickness without requiring pre-drilled holes.
