S-91515A130 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced drilling efficiency with integrated No. 3 drill tip that eliminates pre-drilling requirements in steel and sheet metal
• Maximum material penetration capability of 0.21" thickness for robust fastening in heavy-duty applications
• Optimized load distribution through the wide flanged truss head design that prevents pull-through and improves clamping force
• Reliable thread formation with BSD thread forming technology that creates strong, permanent threads in parent material
• Secure drive engagement with No. 2 Phillips drive that provides positive torque transfer and reduces cam-out
• Full-length threading ensures maximum grip along the entire 3" length for superior holding power

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional performance in steel and sheet metal applications where traditional fastening methods fall short. The innovative combination of thread forming BSD technology and integrated No. 3 drill tip eliminates the need for separate drilling operations, significantly reducing installation time and labor costs. The flanged truss head design provides a wider bearing surface that distributes clamping force evenly, preventing material deformation in thin-gauge applications. With 14 threads per inch and fully threaded construction, these industrial fasteners maintain consistent grip strength throughout their entire length, making them ideal for structural assemblies, HVAC systems, and metal fabrication where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

This 0.216" x 3" tapping screw features precision right-hand threads with fully threaded design and round shank cross-section for consistent performance. Manufactured to BSD thread forming standards with No. 3 drill tip configuration, these screws comply with RoHS 3 (2015/863/EU) regulations for environmental safety. The zinc-plated steel construction ensures corrosion resistance while maintaining the mechanical strength required for industrial fastener applications in steel and sheet metal up to 0.21" thickness.
