As a rough guide, a pilot hole should be between the minor diameter and major diameter of the screw thread. For example: a #6 screw (major diameter of threads ~3.5mm, minor diameter ~2.5mm) would typically need a pilot hole of 2.7-3mm depending on the hardness / toughness / density / lubricity of the material.

How do you determine the drill size for a tapped hole?
As a rule of thumb, for Metric threads, the tapping drill can be calculated by subtracting the pitch from the diameter of the thread. eg for an M5x0. 75 thread the tapping drill is 5-0.75mm = 4.25mm. For Imperial (inch) threads the tapping drill size is calculated in the same way, diameter minus pitch.
