Now, take a stud, and measure how deep the screw
goes into it. Is there sufficient depth in the
brass stud for a 4mm long screw ??? Remember that
the screw is for retention of the module and is
intended to pull the module flat against the stud.

The depth feeler on my calipher won't fit in there,
but you can take a sewing needle, the blunt end,
and use that to take a depth reading. If you have a
drill index, the smallest bit in the drill index will
likely fit in the hole.

You don't want to be cutting the end off the screw
to make it work. With the box of Imperial #2 I've got, I cut the
end off quite a few of them (as a function of application).
My threading tool for the #2 isn't the best, and only
the top portion of a threaded hole works properly, so the
tiny screws have to be cut down in order to work. I typically
use this for building boxes out of Plexiglass or Perspex.
With a thick enough plastic, you can drill a hole for a #2
end-on with the plastic, then thread the plastic and hold two
pieces together with a screw.
