To determine the correct drill bit size for screws, match the drill bit to the screw's shank (the smooth part) diameter for a perfect fit. For softer materials like wood, slightly undersize the bit for a tighter grip. Use this tip: the drill bit should be the same size as the screw's core without the threads. For best results, refer to a drill bit size chart.
