S-90203A528 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Self-drilling capability eliminates pre-drilling steps, saving time and labor costs in steel, stainless steel, and sheet metal applications
• 410 stainless steel construction provides excellent corrosion resistance and durability for demanding industrial environments
• Square drive (No. 3) ensures secure tool engagement and reduces cam-out during high-torque installation
• Thread forming (BSD) design creates strong, permanent threads in base materials without chip removal
• Pan head with rounded profile offers a finished appearance while providing good bearing surface
• Fully threaded 2" length delivers maximum grip range and holding power across the entire fastener
• Compliant with RoHS 3 and REACH regulations ensures environmental responsibility and global market acceptance

Professional Applications & Engineering Value

These No. 12 self-drilling tapping screws are engineered specifically for steel, stainless steel, and sheet metal applications where efficiency and reliability are critical. The 410 stainless steel composition provides superior corrosion resistance compared to carbon steel alternatives, while the thread forming BSD design creates strong, vibration-resistant connections without generating metal chips that could contaminate sensitive equipment. The integrated drilling tip (No. 3) penetrates up to 0.187" maximum thickness, eliminating the need for separate drilling operations and significantly reducing installation time in high-volume manufacturing, metal fabrication, and construction projects. The square drive pan head configuration ensures secure driver engagement and consistent clamping force across a wide range of automated and manual assembly processes.

Specification Summary & Compliance

These self-drilling tapping screws feature a 0.216" thread diameter with 14 threads per inch in right-hand orientation and Class 2A thread tolerances for consistent performance. The BSD (thread forming) tapping screw type follows industry standards for metal fastening applications. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety standards are met for global industrial use.
