Warp 9 M8 x 12 FA Rotor Bolt – DR650

Rotor bolt with an M8 x 12 size designation and an FA marking, for the DR650.

Rotor bolts hold a safety critical part and live in brake dust and spray. They are also torqued into a joint that heat cycles every time you brake hard, so heads corrode and threads pick up. A corroded bolt gives a torque reading that does not reflect the clamp load you are actually getting, which is why fresh ones go in with a new rotor.
