Just a quick update. Borrowed one of those Irwin tools, and it was softer than the wheel bolt so it just mashed all the thread out of it.
However, managed to get 3 of them off by hammering on a socket at a slight angle.
Luckily my old man had some of his ancient socket sets from when he had his CAT D5 when people made tools to last

Just the drivers side front left but it being a right pain, it seems a bit softer then the rest as the socket just chewed the outside of it off!
