I am sure I took mine apart using a nutdriver from my Xcellite System 99 
kit, although I can't rememebr if it was 5.5mm or 7/32" (5.55mm)

In general, better tools, made from stronger metal, are thinner (they 
don't need the thickness to get their strength) and will fit into more 
confined spaces

I did have ome problem like this, though. The PSU for my Panasonic 
handheld computer -- the one with a voltage selector switch for 110V or 
220V mains -- is assemed by 4 deeply-recessed System Zero screws. No idea 
_why_ they used those darn things, but the holes they were down were too 
small for the official System Zero tool to go in. But only just. I ran a 
twist drill down the hole to enlarge it slightly and had no problems 
gettingthe screws out and back (or indeed in replacing the blown fuse inside)
