BMW part number 32321109641 (32-32-1-109-641) is an M6x14 anti-tamper fracture (shear) bolt used on the steering column assembly of classic BMW models produced from 1969 through 1989. Unlike the larger M8 bolts that clamp the ignition lock housing or main column mount, this smaller M6x14 shear bolt secures the steering column trim panel and upper attachment brackets (typically 4 bolts per car). Once tightened to factory torque, the hex head snaps off cleanly to prevent easy access to the steering column mechanism.

To remove old headless shear bolts from an E10 or E21 steering column, use a sharp center punch and hammer to tap the bolt counter-clockwise, or cut a flat slot into the rounded dome with a Dremel. Because factory torque is relatively low and the bolts rarely seize from rust inside the cabin, they usually spin right out once broken loose.
