Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws deliver exceptional performance in demanding sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming A/AB type design eliminates the need for pre-tapped holes, creating stronger threads that resist vibration loosening while reducing installation time and labor costs. The Phillips oval head with standard profile ensures a clean, finished appearance while the 82° countersink angle provides secure seating in various metal thicknesses. Engineered for industrial screw applications, these fully threaded fasteners maintain consistent clamping force across the entire 1-3/4" length, making them ideal for HVAC systems, electrical enclosures, and metal fabrication projects where reliability cannot be compromised.
