That's why I use a ratchet and deep well socket.  I find the bolts sticking 
out on a ROHN 45G to be hazardous, so all of mine have the nuts on the 
inside.

As my tower is climbed often and the torque checked about once a year I have 
little concern about a nut coming off.  The only short coming I find is if I 
want to bring the coax cables and control cables down the inside of a leg. 
Then it takes some precautions going around the bolts.
