Hello hautcoeur,
m3 = approx 3.11mm
m4= approx 4.15mm
those would be min recommended, but in order to get the min actual you would need to pitch to get 2 threads, which is what I would say would be the overall min so say 2mm for the m3, and 3mm for the 4mm approx in order to allow for 2 turns plus some screw clearance.
Thanks, Matt

Hi, thanks for that first reply.
So these are the minimum depth.
But what are the holes diameter?
Thank you

Diameter = 4mm
Tap drill size = 3.3mm
M3 X .5
