Needing to change my brake discs, I was blocked by a nut nut Torx seized, I tried with a 6-point socket, but other than damaging the nut it not been conclusive. I ordered these sockets, received the next day and it worked well, with a long arm, because it was really stuck, the nut is unblocked without damaging themselves. This kind of bush seems essential if you do auto mechanics.
