Broken frunk tub bolts Model S 2013

Hi
Any ideas to remove these 3 bols with thread issues? As you can see on the pictures, I already tried the screwdriver under the bolts’ lip without success.

Thanks in advance for any constructive suggestions.

Cheers

I managed to remove one of the bolts as you can see on the following pictures. I plan on drilling around the remaining bolt with the tool pictured below. Any other idea?

So the fastener has broken loose with the bolt? Could you drip Gorilla Glue down in there to restore it? If they are both metal, JB Cold Weld would be even better.

I still have the tub in there as the left bolt is still stuck. I have not yet chosen the radical path of drilling around. Thanks for the advices, I’ll keep you posted.
