S-94195A349 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling with integrated No. 3 drill tip, saving significant labor time and tooling costs in steel and sheet metal assembly.
• Superior corrosion resistance provided by 410 Stainless Steel material, ensuring long-term reliability in demanding industrial environments.
• Exceptional thread-holding power from the thread-forming (BSD) design, which creates stronger, vibration-resistant connections in metal substrates.
• Streamlined, flush installation with the standard 82° flat head and Phillips drive, ideal for applications requiring a smooth, unobtrusive finish.
• Optimized for rapid, high-volume driving with the common No. 3 Phillips drive size, reducing cam-out and improving assembly line efficiency.
• Maximum material engagement due to the fully threaded 3-inch length, providing consistent clamping force along the entire fastener.
• Compliance with global environmental standards (RoHS 3 & REACH), ensuring they are safe for use in regulated markets and industries.

Professional Applications & Engineering Value

These self-drilling tapping screws are engineered to solve the critical industrial challenge of efficiently joining steel, stainless steel, and sheet metal without separate drilling operations. The 410 Stainless Steel construction offers a robust balance of strength and corrosion resistance, essential for outdoor enclosures, HVAC systems, and metal framing. The thread-forming (BSD) design cold-forms mating threads as it's driven, resulting in zero chip production and a tighter, more vibration-resistant fit than thread-cutting alternatives. This is critical for maintaining joint integrity in machinery and structural applications subject to dynamic loads. The combination of the No. 3 drill tip and specified 82° countersink angle ensures a clean, precise pilot hole and a flush-mounted head, streamlining the assembly process for industrial fastening in high-volume production environments.

Specification Summary & Compliance

This fastener features a 1/4"-14 thread size with a right-hand thread direction and is fully threaded for its entire 3-inch length. The screw is manufactured to the BSD (Thread Forming) standard. This product is confirmed to be compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
