S-92365A475 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with self-drilling tip that penetrates up to 0.22" steel and sheet metal
• Superior corrosion resistance through zinc-plated steel construction for extended service life in industrial environments
• Optimized drive engagement with #3 Phillips drive for secure installation and reduced cam-out during high-torque applications
• Maximum material engagement through fully threaded BSD design ensuring superior holding power in metal assemblies
• Clean flush installation with 82° countersink angle and standard flat head profile for smooth surface finishes
• Reliable thread formation using right-hand thread forming method that creates strong, permanent fastening points
• Precise dimensional consistency with 1/4"-14 thread specification ensuring compatibility with standard industrial components

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in metal fabrication and assembly operations where efficiency and reliability are paramount. The thread forming BSD design creates precise mating threads in steel and sheet metal substrates without removing material, resulting in superior vibration resistance and pull-out strength compared to conventional fasteners. The integrated drilling tip eliminates secondary drilling operations, significantly reducing installation time and labor costs in high-volume production environments. With their #3 Phillips drive and 82° countersink angle, these screws provide secure driving performance and flush mounting ideal for applications requiring smooth surface profiles. The fully threaded 1-1/2" length ensures maximum thread engagement across the entire fastening zone, making them particularly valuable in structural applications where joint integrity is critical.
