S-94059A201 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.098" thickness in steel and sheet metal
• Superior corrosion resistance through zinc-plated steel construction for extended service life in demanding environments
• Weather-tight sealing protection provided by the integrated steel/rubber washer that prevents moisture and contaminant ingress
• Enhanced torque transfer and installation efficiency with external hex drive design and 1/4" head width for secure tool engagement
• Reliable thread-forming performance through BSD tapping method that creates strong, permanent threads in base materials
• Maximum holding power achieved through fully threaded design with 18 TPI for superior grip along the entire 3/4" length
• Consistent installation performance ensured by right-hand thread direction and No. 8 screw size standardization

Professional Applications & Engineering Value

This No. 8 zinc-plated steel tapping screw delivers exceptional value in industrial fastening applications where weather resistance and structural integrity are paramount. The thread forming BSD design creates precise, durable threads in steel and sheet metal substrates without requiring pre-tapped holes, significantly reducing installation time and labor costs. The integrated steel/rubber sealing washer provides critical protection against environmental elements, making these fully threaded screws ideal for outdoor equipment, HVAC systems, and metal fabrication where moisture resistance is essential. The combination of external hex drive and drilling tip allows for high-torque installation while maintaining material integrity, ensuring reliable performance in demanding industrial settings.

Specification Summary & Compliance

This thread forming tapping screw features precise dimensional specifications including No. 8 size with 0.164" thread diameter, 18 TPI thread pitch, and 3/4" length. The screw meets industry standards for BSD tapping screw applications with right-hand thread direction and fully threaded design. Manufacturing complies with standard inch system measurements and includes a flat washer configuration with 1/2" OD. The zinc-plated steel construction and steel/rubber washer materials ensure compatibility with industrial requirements for corrosion resistance and environmental sealing in steel and sheet metal applications.
