Quick help please - stripped wheel nut.

[VintageMA]

After having the wheel nut come loose and almost lose it I blue thread locked all the wheel nuts. When I went to change the wheels last night I got all but 1 nut off. It is on so tight that I stripped a socket wrench and the head of the nut - so there is nothing to grab onto right now.

I've tried heating it up with a blow torch a bit to loosen the thread lock, but I still can't loosen the nut.

FYI - this is the 14-17mm adapters that come with the HPI pre-mounted Phatlines. The metal on the nuts is very soft.
