the entire screw is
threaded, there is not a wider bigger screw head, the screw disappears
completely inside the screw hole.

You are describing a set screw. All you need to do is loosen it. You
don't have to remove it.

Yes it is a set screw. It is used to tighten and held in place the lower
part of a glass door handle. I tried to remove it in order to get an
identical one because the top one was missing. Now I cannot loosen it. I
even tried tapping it hard into the hole and use a plier to clamp on to the
L shaped wrench to no avail. I will try it again tomorrow but instead of
turning it slow I will try to snap just as you suggested and see what
happens.
