Probably sounds silly but use a quality 6 point impact socket ( I prefer Snapon flank drive) grabs the flats not the points of the nut.
Impact always wins over shear force, as long as you can create it.
I have had the occasion to override the pressure switch on my compressor and use a direct port so I’m sending 150 psi to my impact….I’m not safe to be around sometimes…..

I have good news and bad news. I forgot about PSI. I had it at 90 so I turned it up to 160 and they broke free. 9 of them anyway. One broke the socket then rounded off using a second socket. Now what do I do to get that one off? I think there is some kind of socket for that. I need to research it.

That’s the advantage of snap on flank drive…pricey but I buy used and extremely rare too buy new ….I’m not chasing a truck and paying extra. I’ve only broke a couple of snap on tools….and it was very extreme and intended.

My Milwaukee 1/2" drive electric gets things off air won't.

Those are really good…. But will not do what my IR does, but it’s not a fair comparison. 👍
