Pre-drill holes with a 4 mm drill for 25 mm furniture casters and 5 mm drill for sizes 29, 32 and 38 mm. Countersink the drill bit with a 10 mm drill bit about 1 mm deep. Do not pull the screw too hard, as this will reduce the mobility of the wheel. If you choose to use the small screw holes in the base plate, they should also be pre-drilled. Remember to use a screw with a flat head.
