• Superior corrosion resistance from 410 Stainless Steel construction, ensuring long-term reliability in demanding industrial environments.
• Exceptional thread-forming hold with BSD type and fully threaded design creates secure, vibration-resistant fastenings in materials up to 0.21" thick.
• Clean, flush installation is achieved with the standard 82° flat head profile, providing a smooth finish and reducing snag hazards.
• Optimized drive engagement with a Phillips No. 3 drive offers efficient installation and reduces the risk of cam-out.
• High-strength performance in right-hand threaded applications, designed for reliable use in steel, stainless steel, and sheet metal.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring they meet global standards for industrial use.

Professional Applications & Engineering Value

These self-drilling tapping screws are engineered to solve the critical industrial challenge of speed and efficiency in metal fabrication. The 410 Stainless Steel material provides the necessary hardness and corrosion resistance for outdoor or harsh environment applications, from construction frames to HVAC ductwork. The thread-forming (BSD) design and No. 3 drill tip work in tandem to create a strong, pre-tapped thread in the base material as the screw is driven, eliminating the separate drilling and tapping steps. This not only drastically reduces assembly time but also minimizes the risk of misalignment and thread damage, providing a consistently high-quality, high-strength connection in steel, stainless steel, and sheet metal up to the specified 0.21" thickness.

Specification Summary & Compliance

This No. 14 screw features a 0.242" thread diameter with 14 threads per inch and a 4-1/2" length. It is manufactured as a BSD type thread-forming tapping screw with a standard 82° countersink angle for the flat head. The product is confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to stringent international regulations for hazardous substances.
