S-90203A532 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling with integrated No. 3 drill tip that penetrates up to 0.21" thickness in steel and sheet metal, saving significant labor time and tooling costs.
• Superior corrosion resistance provided by 410 Stainless Steel material, ensuring long-term reliability in demanding industrial and construction environments.
• Exceptional thread-holding power through the BSD thread forming design, which creates strong, vibration-resistant threads in ductile metals without generating chips.
• Optimized drive engagement with the square drive (No. 3 size) prevents cam-out and allows for high torque application during installation.
• Full 1-1/2" thread engagement maximizes pull-out strength and distributes clamping force evenly across the entire fastened joint.
• Right-hand threading provides standard, intuitive installation that integrates seamlessly with existing assembly processes.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring they meet international standards for restricted substances.

Professional Applications & Engineering Value

These self-drilling tapping screws are engineered to solve critical fastening challenges in steel, stainless steel, and sheet metal applications. The 410 Stainless Steel construction provides excellent strength and corrosion resistance, while the integrated drill tip completely eliminates the need for separate drilling operations. The BSD thread forming technology creates precise, high-strength threads through material displacement rather than cutting, resulting in zero chip production and superior resistance to vibration loosening. This combination makes them ideal for HVAC systems, metal building construction, and industrial equipment assembly where speed of installation and long-term joint integrity are paramount. The fully threaded design ensures maximum engagement in both thick and thin materials, providing consistent clamping force across diverse application requirements.

Specification Summary & Compliance

These No. 14 size screws feature a 1-1/2" length with fully threaded BSD thread forming design and right-hand threading. The screw meets standard dimensional requirements for industrial fasteners and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The square drive (No. 3 size) ensures positive torque transmission, while the pan head with standard rounded profile provides a balanced combination of bearing surface and clearance.
