I don't remember. Probably a box end wrench. On any bleed screw you need a hose draining into a clear bottle that has brake fluid already in it. The end of the hose needs to be submerged in the fluid in the bottle. This way, when bubbles come out, you see them rise through the fluid in the bottle. Pump until you see no bubbles. You also need to start at the caliper furthest from the mc and work to the closest. Stock prop valves can also cause issues with getting all the air out if the back half of the system.
