Just a wild guess, but they are probably metric. Exactly which screws are you needing? Looks like M5 for the 20mm rails.

Thanks Jim but the holes are 6mm so I got 6mm cap screws and put them in the lathe and cut the cap diameter from 9.85 mm down to 9.5 they fit real nice . No slop when the bolts are in the rail. Getting closer to actually starting this cnc conversion.
