S-94058A544 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance through zinc-plated 410 stainless steel construction for extended service life in harsh environments
• Efficient installation without pre-drilling thanks to the integrated No. 3 drilling tip that penetrates up to 0.21" thickness
• Reliable sealing performance with integrated stainless steel/rubber washer that prevents moisture and contaminant ingress
• Excellent thread retention through BSD thread-forming technology that creates strong, permanent threads in parent material
• High torque transmission capability with external hex drive design that prevents stripping during installation
• Maximum holding power through fully threaded design that provides consistent engagement along the entire length
• Versatile material compatibility specifically engineered for stainless steel and sheet metal applications

Professional Applications & Engineering Value

These zinc-plated 410 stainless steel tapping screws deliver exceptional value in industrial fastening applications where corrosion resistance and sealing integrity are critical. The combination of thread-forming BSD technology and integrated stainless steel/rubber sealing washer addresses common challenges in sheet metal assembly and stainless steel fabrication by eliminating the need for separate washers and pre-tapped holes. The No. 3 drilling tip enables direct penetration into materials up to 0.21" thick, significantly reducing installation time while maintaining structural integrity. The external hex drive ensures reliable torque transmission during high-volume assembly operations, making these fully threaded screws ideal for HVAC systems, electrical enclosures, and metal building components where vibration resistance and environmental sealing are paramount.
