S-94195A249 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Effortless installation with integrated No. 3 drill tip that eliminates pre-drilling, saving time and labor costs in steel, stainless steel, and sheet metal applications.
• Superior corrosion resistance provided by 410 Stainless Steel material, ensuring long-term durability and reliability in harsh industrial environments.
• Enhanced holding power from the thread forming (BSD) design, which creates strong, secure threads in metal for vibration-resistant fastening.
• Clean, flush finish with a standard 82° flat head that countersinks neatly into materials, reducing snagging and improving safety.
• High drilling capacity capable of penetrating up to 0.187" thick materials, making it versatile for various metal thicknesses.
• Wide compatibility with a Phillips No. 3 drive for common tooling, ensuring easy installation with standard industrial drivers.
• Regulatory compliance with RoHS 3 and REACH standards, guaranteeing safe, environmentally responsible components for global supply chains.

Professional Applications & Engineering Value

These self-drilling tapping screws are precision-engineered from 410 Stainless Steel to address common challenges in metal fabrication and assembly. The integrated No. 3 drill tip and thread forming (BSD) design allow for rapid, one-step installation in steel, stainless steel, and sheet metal, eliminating the need for separate drilling and tapping operations. This reduces assembly time, minimizes tool changes, and lowers the risk of misalignment. The fully threaded right-hand configuration and flat head with an 82° countersink ensure a secure, flush fit that withstands vibrations and environmental stressors. Ideal for HVAC, automotive, and construction applications, these screws deliver consistent performance, reduce labor costs, and enhance structural integrity in demanding industrial fastening scenarios.

Specification Summary & Compliance

This No. 12 size screw features a 2-1/2" length with a thread diameter of 0.216" and approximately 14 threads per inch, adhering to standard inch measurements for precision fit. The thread forming (BSD) tapping method and fully threaded shank provide reliable engagement in metal substrates. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures the product meets stringent environmental and safety standards, supporting sustainable and responsible manufacturing practices.
