I'm puzzled as to what Mr. Salehi wants to do here. A screw hole is a round 
hole and would be made with a single drill, i.e., a single pad. If one 
wants a slot, we could discuss that; with such a large drill size multiple 
drill hits side-by-side may be practical. (With smaller holes, overlapping 
holes can break drill bits).

If you want through-board connection, presumably the pads will be assigned 
a net. If they are not, that is why a DRC error is coming up. Or another 
rule is being violated.

Every component pad assigned a net should have a corresponding pin on the 
schematic; to be completely explicit, these pins should all have unique 
names (like MH1, MH2, etc.), but if all the pads have the same name and 
there is only one occurrence of that name in the net list, all the pads 
will be assigned that name. So if you must have multiple pads, it may be 
sufficient to give them all the same name.

Note that if one is using the old Load Netlist method of bringing the 
netlist into the board, there is a bug still remaining with SP6 that can 
cause problems. As I recall, this does not happen when using the Update PCB 
command from schematic.

So I recommend a little more discussion of this issue, or else we might be 
advising Mr. Salehi how to do something which might not be such a great 
idea. Perhaps I have failed to understand, wouldn't be the first time .... :-)
