B-17 GP/HE bombs and fins

1. Can anyone tell me precisely how the fins were attached to the bombs?
I have been unable to tell if the screws shown in some photos I've seen are used to attach the fins or if there is some sort of twist-n-lock arrangement where the screw(s) is only a security device so the fins cannot later come off.
2. In regard to the bomb shackles, it appears there are two levers on them which mate with actuators on the racks. From the cutaway drawing I have seen, it appears ONLY one actuator is required to release the bomb hooks. Is the other used to retain or release the safety wires?
