Professional Applications & Engineering Value

These No. 10 x 3/8" zinc-plated steel tapping screws solve critical fastening challenges in sheet metal applications where traditional fasteners fail. The thread forming technology eliminates the need for pre-tapped holes while creating stronger, more reliable connections through material displacement rather than removal. The flat undercut head with 82° countersink angle ensures flush installation without protrusion, crucial for assemblies requiring smooth surfaces. The Phillips drive system provides efficient installation with standard tools, while the zinc-plated steel construction offers essential corrosion protection for industrial environments. These A/AB tapping screws deliver exceptional pull-out resistance in materials up to 0.025" thickness, making them ideal for HVAC systems, electrical enclosures, and metal fabrication projects where vibration resistance and long-term reliability are paramount.
