S-90203A531 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction for long-lasting performance in harsh industrial environments
• Efficient installation with integrated drilling tip that eliminates pre-drilling requirements in materials up to 0.21" thickness
• Enhanced driving torque transmission through No. 3 square drive design for secure fastening and reduced tool slippage
• Optimized thread engagement with BSD thread forming technology that creates stronger, vibration-resistant connections in metal substrates
• Maximum holding power achieved through fully threaded 1-1/4" length design for consistent load distribution
• Secure seating provided by pan head style with standard rounded profile for reliable flush mounting
• Environmental compliance assurance meeting RoHS 3 and REACH standards for sustainable manufacturing practices

Professional Applications & Engineering Value

These No. 14 self-drilling tapping screws deliver exceptional engineering value in metal fabrication and construction applications. The 410 stainless steel composition provides excellent corrosion resistance, making them ideal for exterior applications or environments with moisture exposure. The integrated drilling tip (No. 3 type) eliminates the need for separate drilling operations, significantly reducing installation time and labor costs in steel, stainless steel, and sheet metal assemblies. The BSD thread forming technology creates precise, strong threads without generating chips, preventing contamination in sensitive equipment while providing superior pull-out resistance. The combination of square drive and pan head design ensures reliable torque transmission during installation, minimizing the risk of fastener failure in high-vibration industrial settings.
