S-94625A425 Length 1 1/2" 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 security and tamper resistance with specialized T20 Torx drive requiring matching tool access
• Efficient installation in steel and sheet metal through self-drilling tip design that eliminates pre-drilling requirements
• Maximum material penetration capability with drilling tip engineered for up to 0.15" thickness in metal substrates
• Optimal flush mounting with standard 82° flat head profile that seats perfectly in countersunk applications
• Superior thread engagement and holding power through fully threaded thread-forming design that creates strong, permanent fastenings
• Reliable performance in right-hand thread applications with precise No. 10-16 thread configuration for consistent fastening torque

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in metal fabrication and assembly operations where security, durability, and installation efficiency are paramount. The thread forming design creates stronger, more reliable threads in parent material without chip formation, making them ideal for steel and sheet metal applications where vibration resistance is critical. The combination of tamper-resistant T20 Torx drive and self-drilling tip significantly reduces installation time and tool requirements while providing security against unauthorized access. The fully threaded configuration ensures maximum holding power across the entire fastener length, while the 82° countersink angle provides clean, flush finishes in professional metalworking projects.
