I need to drill one out on a car... do I need cobalt drills or is it soft steel?
Thanks, and yeah... they had 10mm of diameter and 14mm of depth to put in a serious allen or torx hole... and they chose to thread-lock in with a 5mmx5mm allen socket. Not their finest engineering moment :- ).Definitely not hardened, I've had to drill out several. Friggen insane choice of fastener in that environment.
I don't think it's Saab, I think it's mechanics. That screw goes in finger tight. It's just there to position the rotor, and it can't go anywhere once the wheel is on. Put a little anti-seize on it then turn it in with a screwdriver and it'll probably come out with one. I think you get these impact wrench jockeys who hammer on it and then you've got an issue.Definitely not hardened, I've had to drill out several. Friggen insane choice of fastener in that environment.
