Or you could try & cut a new grove in the head of the screw with a hammer & chisel or such like. Then just unscrew it I have had to do this before on my carb top screws. I did eventually get them out with no damage. Using a drill would be the last option! :)
A hammer and chisel would be my last option on a somewhat thin and brittle brake mc cover lol. Not to mention that but its most likely countersunk making that a bit tougher (although not impossible). Easy outs is an option but it's a small screw, good luck with that.
Just out of curiosity why would a drill be someones last option? Just go slow and you'll be fine.
If you drill the heads off of these, they will usually come out with fingers. The head of the bolt appears to sieze in place. Once the tension is off the screw, no big deal.
PS - if you drill it out, start with a pretty small drill bit...guessing something around 7/64. Do NOT use a bit the size of the screw head. You may end going to a little larger bit and drilling it again but you're only drilling a very small amount of material.
