Hammer and chisel might be easier?
Probably a bit late for you, but don't round them off?
Soak them in WD40/plusgas for a bit before you do anything else. Clean ALL of the crap out of the heads of the bolts so that your socket bit can
engage fully. Put the bit in, and give it a good sharp thump on the end with a hammer before you try turning anything.
I've never had a problem doing it this way, even after years of playing with VW's and the silly 12-point XZN bits they use

Start with hammer and chisel to start. To close to tank to grind unless its a last resort

If it is at the diff end of the drive shaft remove the diff back plate and take the circlips off the end of the driveshaft and remove from diff. Take
to the workbench and cut the heads off the bolts with a grinder.

Angle grind the end of the bolts off, remove the Lobro then use stud extractor to remove the stubs (or in my case lots of penetrating oil and some
water pump pliers)....

bolt removal
if you know the dia of the bolts drill off the heads ,start with a old drill first to to knock off the edges on the torx then a nice slow drill speed
some cutting oil and a fresh colbalt drill should sort you out ,knock off the heads , if you want to go for the stud exstracker then go for the snap
on type or sim they are the best trust me we use em daily .

All together now
Cut the heads off with the grinder, remove the joints and there is about 2 inch of stud left to get hold of with the Mole grips. Replace with Allen
head bolts. Hit them square on the head with the hammer before you try to undo them next time.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

WEAR GLOVES !!
BE CAREFUL.
Still struggling here with restricted movement in the finger that I messed up with the angle grinder. It was my own fault, but being careful is the
answer.
Take care.

Funnily enough I've ALWAYS managed to undo these bolts when rounded off with a GOOD pair of Mole Grips.
Beware of the Goldfish in the tulip mines. The ONLY defence against them is smoking peanut butter sandwiches.

Before things get too brutal, a large nut welded over the head ALWAYS get it out, a combination of better grip and leverage and the heat which beaks
the corrosion bond on the threads.
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation
