S-94195A243 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Self-drilling capability eliminates pre-drilling steps, saving time and labor costs in steel, stainless steel, and sheet metal assemblies.
• 410 Stainless Steel construction provides excellent corrosion resistance and durability for demanding industrial environments.
• Thread forming (BSD) design creates strong, secure threads in metal substrates, reducing the risk of stripping and improving vibration resistance.
• No. 3 Phillips flat head allows for a flush, clean finish and easy installation with common driving tools.
• 82° countersink angle ensures a precise, seated fit in standard countersunk holes for a professional appearance.
• Fully threaded 1-3/4" length offers maximum grip and holding power across the entire fastener engagement area.
• Compliance with RoHS 3 and REACH ensures environmental safety and meets international regulatory standards for industrial use.

Professional Applications & Engineering Value

These No. 12 self-drilling screws are engineered to address common challenges in metal fabrication, such as the need for rapid assembly and reliable fastening without secondary operations. The 410 stainless steel material offers a balance of strength and corrosion resistance, ideal for outdoor or harsh environment applications. The thread forming action of the BSD tapping screw type cold-forms mating threads in the material, which work-hardens the surrounding metal and provides superior resistance to loosening under vibration—a critical advantage in automotive, HVAC, and construction assemblies. The integrated drill tip (No. 3 type, 9/32" length) efficiently penetrates up to 0.187" thick steel, stainless steel, and sheet metal, streamlining production lines and reducing tooling requirements.

Specification Summary & Compliance

This fastener features a thread diameter of 0.216" with 14 threads per inch and a right-hand thread direction. It is fully threaded with a standard flat head profile and Phillips No. 3 drive. Manufactured to industry standards for tapping screws, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial supply chains.
