Warp 9 M6 x 13 BHT Rotor Bolts – 690

Rotor bolts with M6 x 13 and BHT designations, for 690 applications.

These bolts clamp the rotor to the hub, a joint that heat cycles every time you brake hard. Corrosion in the thread changes the friction, so the torque you read is no longer the clamp load you get. Fitting new bolts with a new rotor is the cheap half of the job.
