S-90203A511 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling with integrated No. 2 drill tip that penetrates up to 0.09" 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 environments.
• Exceptional thread retention through BSD thread forming technology that creates strong, vibration-resistant connections without chip removal.
• Secure installation with square drive (No. 1 size) that prevents cam-out and allows for high torque application during fastening.
• Optimized head design featuring a standard pan head with 0.27" diameter for excellent bearing surface and 0.097" low profile for space-constrained applications.
• Full 1-inch threading provides maximum grip length and load distribution across the entire fastener engagement area.
• Regulatory compliance assurance with RoHS 3 and REACH standards, meeting international environmental and safety requirements for industrial use.

Professional Applications & Engineering Value

These No. 6 self-drilling tapping screws deliver exceptional value in metal fabrication and assembly operations where speed and reliability are critical. The 410 stainless steel construction provides excellent corrosion resistance for outdoor equipment, HVAC systems, and industrial machinery exposed to harsh conditions. The BSD thread forming technology creates stronger threads in parent material by cold-forming rather than cutting, eliminating chips and reducing the risk of contamination in sensitive applications. With the ability to drill through 0.09" thick steel, stainless steel, and sheet metal, these fasteners streamline production by combining drilling and tapping into a single operation. The square drive ensures positive engagement with installation tools, preventing slippage and damaged screw heads during high-volume assembly. The fully threaded design and 20 threads per inch configuration provide optimal clamping force distribution across the entire engagement length.

Specification Summary & Compliance

These self-drilling tapping screws feature precision No. 6 size with 1" length and 0.138" thread diameter with 20 threads per inch in right-hand direction. The fasteners maintain Class 2A thread tolerances for consistent performance and are manufactured to BSD thread forming standards. Compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest international standards for hazardous substance restrictions in industrial components.
