I can't remember the thread pitch of the half shaft but do yourself a favour, and throw away those puss ridden exuse for nuts and get a couple of nylock nuts.
I am actually impressed that you got them off without smashing them to peices like I did. I am not sure of the torque required as I asked the guy doing the cars first wheel alignment to check them and he did them up with a rattle gun.
