#4 - 1/2 Phillips Flat Head Sheet Metal Self Tapping Screws (Zinc-Plated Steel) are designed with sharp cutting threads to create threading while being installed. Unlike self drilling (Tek) screws, however, a pilot hole is needed to start the drilling process. Tapping screws are used in just about any material, especially sheet metal, wood, and plastic applications. The flat head allows the screw to sit flush with the surface leaving a clean, smooth finished result.
