[AT] OT...Need some advice on old metal building

[charlie hill]

Ken, I started to say the same thing earlier but if they have nuts on the 
inside of the framing the frames are probably drilled and the bolt/screw 
will just spin instead of
popping off.  It's worth a try though.  Big, strong drill motor and one of 
those slotted screw driver bits with the shield over it to keep it centered 
should to the job.

Have you tried tightening them instead? That will probably snap them off.
Not sure if that's what you're looking for but...

We put a hopper bin together with a dome shaped slotted screw with square
nuts and we could break those silly things with hand tools. Where the head
attached to the screwed part was soft, weak or whatever and would just pop
off if you reefed on it with a large screwdriver, let alone an open end
wrench. Made air tools useless since we couldn't set the torque low enough.
A butterfly wrench might work now but Dad didn't have one back in the day.
