S-94195A424 Length 7/8" Tapping Screws

Key Features & Benefits at a Glance

• Self-drilling tip eliminates pre-drilling, saving time and labor costs in steel, stainless steel, and sheet metal applications.
• 410 Stainless Steel construction provides excellent corrosion resistance and durability for long-lasting performance in demanding environments.
• Thread forming (BSD) design creates strong, secure threads in metal, reducing the risk of stripping and ensuring a reliable hold.
• Phillips flat head with 82° countersink angle allows for a flush, clean finish, enhancing the aesthetic and safety of the assembled product.
• Capable of drilling through materials up to 0.14" thick, offering versatility for various industrial and construction projects.
• Fully RoHS 3 and REACH compliant, ensuring environmental safety and meeting international regulatory standards for industrial use.
• Consistent No. 12 screw size and 14 TPI thread pitch ensure reliable performance and interchangeability in automated or high-volume assembly.

Professional Applications & Engineering Value

These self-drilling tapping screws are engineered to solve common industrial fastening challenges, such as the need for speed and reliability in metal assembly. The 410 Stainless Steel material offers a balance of strength and corrosion resistance, ideal for HVAC, construction, and metal fabrication where exposure to harsh conditions is a concern. The integrated drill tip (No. 3 type) and thread forming (BSD) technology allow the screw to drill, tap, and fasten in one operation, significantly reducing installation time and minimizing tool wear. This makes them highly efficient for steel, stainless steel, and sheet metal applications, providing a secure, vibration-resistant connection that maintains integrity under stress, enhancing overall project durability and reducing maintenance needs.

Specification Summary & Compliance

This screw features a No. 12 size with a 0.216" thread diameter and 14 threads per inch (TPI) in a right-hand thread direction, fully threaded for consistent grip. The flat head with standard profile and 82° countersink angle ensures proper seating. Manufactured to typical industrial standards for tapping screws, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of hazardous substances and suitable for global industrial supply chains.
