Kanishka, you didn't mention the type of screw which diameter you want to know. we are using watch screw for EEG electrodes diameter ( head .5 mm and tail .25mm) this is the best screw size for preparing EEG electrode.
for noise issues and in order to get a good record you place a anchoring screw diagonally, diameter ( stainless steel screw diameter head 2mm and tail 1mm).

For EEG, the electrode should have a head of 0.5 mm and tail of 0.25 mm.
