I have some bolt extractors that are left hand threading, but need pilots drilling first and even then they are notorious for breaking off themselves, leaving a very hard to drill out section stuck in the bolt, making the job harder.
I have some small metal plate offcuts I'm going to try and slip into the very small gap under the captive nut to jam it in place and try and undo the bolt.
