If unsure, send your VIN, and we’ll check for you fast.

Common uses:

Mounting brake discs (rotors) to hub/knuckle

Often required during disc, pad, or calliper replacement

Always check your old bolt and consult a fitment chart,

or message with your VIN for confirmation.

Installation Tips

Use a high-quality Allen/hex key for installation—ensure perfect fit to avoid stripping head

Clean hub/calliper mount threads before installation (remove rust/debris)

Apply a dab of anti-seize or copper grease to thread if not factory-coated

Torque to manufacturer spec (typically 28–35 Nm, but check your BMW manual)

Replace bolts if head shows signs of rounding, rust, or stretching—never reuse damaged hardware
