S-94195A411 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior drilling performance with No. 2 drill tip and 3/16" length for efficient penetration into steel, stainless steel, and sheet metal up to 0.09" thickness
• Exceptional corrosion resistance provided by 410 stainless steel material, ensuring long-term reliability in harsh industrial environments
• Optimized thread forming design (BSD type) creates strong, permanent threads in base materials without pre-drilling, reducing installation time and labor costs
• Precise countersinking capability with 82° flat head profile for flush mounting and clean finished appearance in assembled products
• Enhanced driving efficiency through Phillips No. 2 drive style, providing secure torque transfer and reducing cam-out during installation
• Full threading along 1 3/4" length ensures maximum grip and holding power throughout the entire fastener engagement
• Regulatory compliance assurance with RoHS 3 and REACH standards, meeting international environmental and safety requirements

Professional Applications & Engineering Value

These No. 6-20 self-drilling tapping screws deliver exceptional value in metal fabrication and assembly operations where time efficiency and joint integrity are critical. The 410 stainless steel construction provides excellent corrosion resistance, making these fasteners ideal for outdoor equipment, HVAC systems, and industrial machinery exposed to moisture and chemicals. The combination of thread forming technology (BSD type) and integrated drilling tip eliminates multiple installation steps, significantly reducing labor costs in high-volume production environments. The 82° countersink angle and flat head design ensure smooth, flush finishes in sheet metal applications, while the fully threaded configuration maximizes pull-out resistance in steel and stainless steel substrates up to 0.09" thickness. These features collectively address common assembly challenges including material galling, installation speed, and long-term fastener reliability.

Specification Summary & Compliance
