Professional Applications & Engineering Value

These 18-8 stainless steel oval head tapping screws deliver exceptional engineering value in demanding sheet metal applications where corrosion resistance and permanent fastening are critical. The thread forming technology eliminates the need for pre-tapped holes, reducing installation time and labor costs while creating stronger thread engagement than cutting alternatives. The Phillips No. 2 drive provides secure tool engagement during high-torque installation, minimizing cam-out incidents that can damage screw heads and disrupt production flow. The combination of fully threaded design and precise 15 TPI thread pitch ensures maximum holding power across the entire fastener length, making these A/AB tapping screws ideal for HVAC systems, electrical enclosures, automotive components, and industrial machinery where vibration resistance and long-term integrity are paramount.

Specification Summary & Compliance
