S-90203A520 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Efficient self-drilling capability with a 1/4" drill tip that eliminates pre-drilling, saving time and labor in steel, stainless steel, and sheet metal applications.
• Superior corrosion resistance due to 410 Stainless Steel construction, ensuring long-term durability in harsh industrial environments.
• Enhanced driving torque and reduced cam-out with the square drive (No. 2 size), providing secure installation and minimizing tool slippage.
• Strong, reliable thread formation through the thread forming (BSD) design, which creates robust, vibration-resistant threads without chip removal.
• Full-length threading for maximum grip and holding power across the entire 1-1/2" length, improving fastener stability in assembled materials.
• Wide material compatibility, specifically engineered for use in steel, stainless steel, and sheet metal up to 0.15" thickness, offering versatile application solutions.
• Compliance with environmental regulations, meeting RoHS 3 and REACH standards, ensuring safe and sustainable use in global markets.

Professional Applications & Engineering Value

These No. 10-16 self-drilling tapping screws are engineered to address common industrial challenges such as time-consuming pre-drilling and thread failure in metal assemblies. Made from 410 Stainless Steel, they offer excellent strength and corrosion resistance, ideal for outdoor or corrosive environments. The thread forming (BSD) design and fully threaded configuration ensure secure, vibration-resistant fastening in steel, stainless steel, and sheet metal, reducing the risk of loosening under stress. The integrated drill tip (No. 3 type) allows for quick penetration up to 0.15" thickness, streamlining installation in HVAC, automotive, and construction applications while maintaining high thread integrity and load distribution.

Specification Summary & Compliance

This screw features a No. 10-16 thread with a 0.19" diameter and 16 threads per inch, adhering to standard inch measurements for precision. The pan head with square drive (No. 2) ensures easy installation, and the fully threaded, right-hand design provides consistent performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial use without hazardous substances.
