Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws are precision-engineered for demanding sheet metal applications where reliability is critical. The thread forming technology eliminates the need for pre-tapped holes, creating stronger threads by displacing material rather than cutting it. This prevents loosening from vibration and provides excellent resistance to pull-out forces. The pan head design with a No. 2 square drive allows for high torque application during installation, making them ideal for HVAC systems, electronic enclosures, and automotive panels where a flush finish and corrosion resistance are essential. Fully threaded for maximum engagement, these screws deliver consistent performance in metalworking and fabrication projects.

Specification Summary & Compliance

This No. 8-15 x 2-1/2" tapping screw features a 0.164" thread diameter with 15 threads per inch, manufactured to standard A/AB thread forming specifications for sheet metal. The screw is fully threaded with a pointed tip for easy starting and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring they are free from hazardous substances. Designed for use with a No. 29 drill bit (0.136" diameter) in materials up to 0.025" thickness, these screws provide reliable performance in industrial fastening applications.
