Rotor Retaining Screw, BMW - 34111123072

The rotor retaining screw on each brake rotor may need to be replaced whenever the rotor is removed. These screws are often over-tightened which causes the soft metal to round out or strip inside the hex. These only need to be finger tight to keep the rotor from shifting when the wheel is removed. Since most brake rotors do not come with this screw you should pick up the required quantity plus a few spares.

This can be used on a front or rear brake disc. And some models will use a different screw on the opposite axle.

Sold per screw but note that some models have two of these per rotor.
