S-90203A121 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Self-drilling capability with No. 3 drill tip eliminates pre-drilling steps, saving labor time and reducing assembly costs in aluminum and sheet metal applications.
• Superior corrosion resistance from 18-8 stainless steel construction ensures long-term reliability in harsh or humid industrial environments.
• High thread engagement through fully threaded design provides maximum pull-out resistance and vibration resistance in thin materials.
• Efficient installation with No. 2 square drive offers superior torque transmission and reduced cam-out compared to Phillips drives.
• Optimized penetration drills through up to 0.15" thickness in one operation, ideal for standard gauge sheet metal and aluminum panels.
• Secure fastening through thread forming action creates strong, permanent threads without chip removal in ductile materials.
• Regulatory compliance with RoHS 3 and REACH standards ensures environmental safety and global market acceptance.

Professional Applications & Engineering Value

These self-drilling tapping screws solve critical challenges in metal fabrication and assembly operations. The combination of 18-8 stainless steel material and thread forming design eliminates the need for separate drilling and tapping operations, significantly reducing installation time while creating strong, reliable threads in aluminum and sheet metal applications. The No. 3 drill tip geometry ensures clean penetration without workpiece damage, while the fully threaded configuration maximizes thread engagement in thin materials where pull-out strength is critical. The square drive system prevents tool slippage during high-torque installation, making these fasteners ideal for production environments where efficiency and reliability are paramount.

Specification Summary & Compliance

These screws feature precision No. 10-16 thread with 0.19" diameter and 16 TPI thread pitch, manufactured to standard inch system tolerances. The pan head design with 0.373" diameter provides good bearing surface, while the 2" length offers versatile fastening depth. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet international standards for restricted substances.
