S-92970A208 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with its integrated drilling tip, saving time and labor costs in steel, stainless steel, and sheet metal assemblies.
• Superior torque transmission and tamper resistance via the T20 Torx drive, reducing tool slippage and enhancing installation security in high-vibration environments.
• Excellent corrosion resistance and durability from 410 Stainless Steel construction, ensuring long-term reliability in demanding industrial conditions.
• Strong, reliable thread formation using the thread forming (A/AB) method, which creates robust, strip-resistant threads in ductile metals.
• Full-length threading for maximum grip and holding power along the entire 1-1/4" length, providing consistent clamping force.
• Precision drilling capability penetrates up to 0.098" thick materials, ideal for standard sheet metal and light-gauge steel applications.
• Wide compatibility with a No. 8 screw size and 18 TPI thread, designed for common industrial fastening needs in various metals.

Professional Applications & Engineering Value

This 410 Stainless Steel self-drilling tapping screw is engineered to streamline assembly processes in metal fabrication and industrial maintenance. Its drilling tip and thread forming design allow direct installation into steel, stainless steel, and sheet metal without pilot holes, significantly reducing preparation time and the risk of misalignment. The T20 tamper-resistant Torx drive ensures high torque application with minimal cam-out, crucial for automated or repetitive fastening operations. Made from 410 Stainless Steel, it resists oxidation and weathering, making it suitable for outdoor enclosures, HVAC systems, and machinery where corrosion resistance and vibration resistance are critical. The fully threaded No. 8 x 1-1/4" configuration provides uniform stress distribution, preventing loosening under dynamic loads and ensuring a secure, long-lasting fasten in demanding B2B environments.

Specification Summary & Compliance
