S-90064A151 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced driving efficiency with 1/4" external hex head design providing secure tool engagement and reduced cam-out
• Self-tapping capability through thread-forming BSD design eliminates need for pre-tapped holes, reducing installation time and labor costs
• Maximum material penetration with specialized drilling tip that cuts through up to 0.09" thickness in steel and sheet metal applications
• Optimized thread engagement with 20 TPI fine threading and fully threaded shank ensures superior holding power and vibration resistance
• Improved load distribution through integrated flange design that eliminates the need for separate washers while providing larger bearing surface
• Reliable fastening performance with right-hand thread direction and No. 6 screw size engineered for consistent results in metal assembly applications

Professional Applications & Engineering Value

These No. 6 zinc-plated steel tapping screws deliver exceptional value in metal fabrication and assembly operations where speed, reliability, and corrosion resistance are critical. The thread-forming BSD design creates precise mating threads in parent material without chip formation, eliminating the risk of contamination in sensitive electrical or mechanical systems. The combination of external hex drive and No. 2 drill tip enables rapid installation in steel and sheet metal up to 0.09" thickness, significantly reducing assembly time while maintaining consistent clamping force. The fully threaded configuration ensures maximum engagement throughout the fastened materials, while the integrated flange provides superior load distribution without additional components. These characteristics make these tapping screws ideal for HVAC systems, electrical enclosures, automotive components, and industrial equipment where vibration resistance and long-term performance are essential.
