One thing I have came up with for hard to remove screws is to take an old
flat file and grind the tip so its a perfect fit for the screw slot. grind
it with a concave tip so it will not cam out. Now insert the blade int the
slot and apply pressure and use an adjustable wrench on the file to rotate
One other is to get and old jennings brace bit and grind a screwdriver tip
on it and use the brace to turn the screw out ..good luck mjh
If these are standard pan head sheet metal screws then a pair of vice grips
will do the job, assuming you can grab the head.
If they are flat head, a brace equipped with a hardened screw driver bit is
probably your best bet.
IMHO, this is not the time for power tools.
