S-94058A319 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated 410 stainless steel construction for extended service life in harsh environments
• Integrated weatherproof sealing through the stainless steel/rubber washer that prevents moisture ingress and maintains joint integrity
• Self-drilling capability with No. 3 drill tip that eliminates pre-drilling requirements in stainless steel and sheet metal up to 0.187" thickness
• High-torque installation enabled by external hex drive design for secure fastening and reduced tool slippage
• Reliable thread formation through BSD thread forming design that creates strong, vibration-resistant threads in base materials
• Full-length threading ensures maximum grip strength and uniform load distribution along the entire 3" length
• Regulatory compliance with RoHS 3 and REACH standards for safe use across industrial applications

Professional Applications & Engineering Value

These No. 12 zinc-plated 410 stainless steel tapping screws address critical challenges in metal fabrication and construction applications. The combination of thread forming BSD design and self-drilling tip eliminates multiple installation steps, significantly reducing assembly time and labor costs in stainless steel and sheet metal projects. The fully threaded configuration ensures maximum pull-out resistance, while the integrated sealing washer provides essential protection against environmental elements that can compromise joint integrity. The external hex drive delivers superior torque transmission for high-strength connections, making these tapping screws ideal for HVAC systems, electrical enclosures, and structural assemblies where vibration resistance and long-term reliability are paramount.
