S-94195A230 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Self-drilling capability eliminates pre-drilling steps, saving significant labor time and reducing installation costs in steel and sheet metal assemblies.
• 410 Stainless Steel construction provides excellent corrosion resistance and durability for long-lasting performance in demanding industrial environments.
• No. 3 drill tip with 9/32" length ensures quick penetration and clean hole creation in materials up to 0.187" thick.
• Thread forming (BSD) design creates stronger, more secure threads in ductile materials, offering superior vibration resistance and pull-out strength.
• 82° countersink angle with flat head provides a flush finish when installed, improving safety and aesthetic appearance in finished products.
• Fully threaded right-hand design maximizes grip length and holding power across the entire fastener engagement area.
• RoHS 3 and REACH compliance ensures environmental responsibility and regulatory acceptance for global industrial applications.

Professional Applications & Engineering Value

These self-drilling tapping screws are engineered specifically for steel, stainless steel, and sheet metal applications where efficiency and reliability are paramount. The 410 stainless steel material offers optimal balance between corrosion resistance and mechanical strength, while the thread forming BSD design eliminates chip removal issues common in traditional tapping operations. The integrated No. 3 drill tip with precise geometry ensures consistent performance through various material thicknesses up to 0.187", making these Phillips flat head screws ideal for HVAC systems, metal building construction, electrical enclosures, and industrial equipment assembly where speed of installation and long-term fastener integrity are critical engineering considerations.
