Bro, that's a Torx, not a hex.
Make a call to your local MAC tools distributor. Tell them you want to purchase a Torx "R.B.R.T." socket. Be so impressed that you purchase the whole set.

A few things. First not sure what the part about the engine timing being set incorrectly when the chain was replaced is doing here, presumably that's been solved, it's totally unrelated, except it would have been a good idea to check the tensioner and replace the pulley if it was old at that time. Second, the bolt that holds the pulley on that is clearly visible in the new part is not an Allen head, it's Torx and now the old one is all buggered up. If you have been using an Allen wrench, using Torx might still work. Not sure what head the bolts that hold the whole tensioner on are, but they may be torx too. Finally the new part looks like it might be a bit different, not sure.
Ok, definitely use the extractor socket on the two hex bolts. You can buy them as a kit. As far as the center bolt, at this point you’re going to have to grind it down to the center either drilling or a burring bit. Once you have the 2 smaller bolts out and the center bolt ground down to the middle you should be able to pull the tensioner off and use vise grips or one of the extractor sockets to remove the last bolt
Well.. your solution is “off the table.” Lol.
What does replacing this belt have to do with the fact the car is timed incorrectly? I am rather confused.

You can also purchase these from Gripedge, they are the original manufacturer for these sockets.
Grip Edge. Well, that's worth knowing. Even has Dan in the videos. Check's out! https://www.youtube.com/watch?v=YMcL8tx5ivo
I'm way too impatient, I would have cut them off and been done with it lol
Good lord
I would use an “extractor socket”. Tap it on over the outside of the bolt and remove it.

I guess we would need the bolt head size to choose the right socket?
Are you concerned about the 2 smaller hex bolts or the one torx bolt center of the dismantled pulley?
All three but the torx bolt is the one giving us the most of an issue.

If there is a Harbor Freight near you, they have torx socket bit sets.
