S-90694A817 Length 3" FM Approved Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black epoxy coating that protects against rust and extends service life in demanding environments
• Exceptional holding power through thread forming technology that creates strong, permanent threads without pre-drilling in steel and sheet metal
• Optimized drilling performance with self-drilling tip that penetrates up to 0.047" thick materials, reducing installation time and labor costs
• Enhanced drive stability with No. 3 Phillips drive that minimizes cam-out and ensures secure fastening during high-torque applications
• Full-thread engagement along the entire 3" length provides maximum pull-out resistance and vibration resistance in structural applications
• Industry compliance assurance with FM Approved certification that meets rigorous safety and performance standards for industrial use
• Versatile application capability designed specifically for steel, insulation, and sheet metal with consistent 13 threads per inch for reliable performance

Professional Applications & Engineering Value

These black epoxy coated steel tapping screws deliver exceptional engineering value through their specialized thread forming design and corrosion-resistant construction. The combination of fully threaded No. 15 screws with self-drilling tips eliminates the need for separate drilling operations in steel and sheet metal applications, significantly reducing installation time and labor costs. The black epoxy coating provides superior protection against environmental factors that typically compromise fastener integrity in industrial settings. With their 0.255" diameter and 3" length, these screws maintain consistent holding power through vibration-prone applications while the rounded pan head design distributes clamping force evenly. Ideal for HVAC systems, electrical enclosures, and structural assemblies, these FM Approved screws ensure reliable performance where safety and durability are paramount concerns.
