Pilot holes for screws is the minimum or slightly less diameter(shaft diameter without threads).

For nails about 1/2 to 3/4 nail diameter.

For anchors it should on the label on the box/bag they came in. If no label/instructions, use a slightly smaller diameter than maximum shaft size. You should need to push hard to get the anchor in fully.
