S-91715A134 10-24 x 1/2" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior Material Protection: Black zinc-plated steel construction offers excellent corrosion resistance, extending service life in demanding industrial environments.
• Efficient Self-Tapping Design: F-Type thread cutting technology eliminates the need for pre-tapped holes, reducing installation time and labor costs in materials like aluminum and sheet metal.
• Optimized Drive Performance: Phillips No. 2 drive ensures secure tool engagement and reduces cam-out risk for consistent, reliable fastening.
• Enhanced Grip and Holding Power: Coarse UNC 10-24 thread profile provides superior pull-out resistance in soft metals and plastics, ensuring long-term joint integrity.
• Versatile Material Compatibility: Specifically engineered for use in aluminum, brass, cast iron, and sheet metal, offering reliable performance across multiple applications.
• Full Thread Engagement: Fully threaded design maximizes contact surface area for stronger, more distributed load bearing in assembled components.
• Standardized Pan Head Profile: Rounded pan head design provides a balanced bearing surface while maintaining a low-profile appearance in finished assemblies.

Professional Applications & Engineering Value

These thread cutting tapping screws deliver exceptional value in metal fabrication and assembly operations where time efficiency and joint reliability are critical. The F-Type thread cutting technology creates precise mating threads in aluminum, brass, cast iron, and sheet metal without requiring pre-tapped holes, significantly reducing installation steps and potential cross-threading issues. The black zinc-plated steel construction provides a durable barrier against corrosion in industrial environments, while the coarse UNC thread pattern ensures maximum resistance to vibration loosening. The combination of Phillips drive and fully threaded design allows for quick installation and optimal load distribution, making these screws ideal for high-volume production environments where consistent performance and assembly efficiency are paramount.
