Self-drilling Phillips pan head sheet metal screws, often referred to as “tek screws,” feature a drill-bit-like tip that drills and taps its own hole in one step. This eliminates the need for pre-drilling, making them highly efficient for fastening metal to metal or metal to other materials like wood or composites. The drill point is typically rated for specific material thicknesses (e.g., up to 0.25″ mild steel).
