I just messed up a hex screw on my 190 e 2.3 1987 mercedes. While changing the rear rotors on my 190 e 2.3 in ran into a problem just a i was re assembeling the the wheel hub unit. While tightening up the hex screw with my allen wrench i ended up stripping the heard of the screw, now the allen wrench tool just spins when i apply pressure to tighten the rotor to the hub. Is there a way that i can get the screw out so that i can replace it with a new screw. What tools do i need to take take out the striped hex screw?
Also will comprimise my driving safety if that screw is not screwed in tight on the rotor.
