Replaced rotors and pads on the 08. One side had a rounded out hex and while the 5mm socket went in snug, the screw wasn’t budging. I heated it up and tapped it w/a punch just to free up any rust, over tightening. Still not budging.
So I went to a T40 torx socket and sledge tapped that in till it was set without holding. Put the ratchet on it and it turned. I was afraid I’d have to drill it out or create a new hex opening, which doesn’t work as easy as it looks on YouTube with punches.
Probably not a new trick, but being the torx has more bite than a hex and slightly larger ID, it’s worth a try.

I had a similar experience with my 1995 900SE. I ended up using "bolt extractor" that normally doesn't work well at all but in this case, after hammering it in, it had enough grip to take out the index.

Impact drivers work pretty well on those index screws, too. I've rounded off a couple with a ratchet and hex bit, but my impact driver always seems to zip them out pretty easily. My 2000 9-5 came with one that someone had drilled out, all the way through the shank. I had to take a cold chisel and a hammer and tap out the remaining threads, but then I was able to put a new screw in.

Those little impact drivers that come in the sets of power tools are a gift from the gods as far as getting index screws out.
Another tip would be to thoroughly clean out the head as well as possible.
