Abstract: A driver-specific back-out prevention mechanism is disclosed that includes a screw and a body. A first driver can be used for coupling and decoupling the screw with the body, and a second driver can only be used for adjusting the position of the screw in the receiving body. The body includes a cavity for receiving a head of the screw, with the cavity having an inward flange. The screw includes upper and lower sockets, with a channel extending though the head from the lower socket and a lock body disposed in the channel. Engagement with the first driver allows the locking body to move such that the fastener can be inserted and removed from the body. Engagement with the second driver displaces the locking body such that the locking body interferes with the flange such that screw fastener cannot be removed from the body by the second driver.

Abstract: A tool for removal of a spring clip from a nut plate assembly includes an inner sleeve having a first cleat configured to engage a first end of a spring clip and an outer sleeve having a second cleat configured to engage a second end of the spring clip, the outer sleeve being rotatably disposed around a portion of the inner sleeve. The tool includes first and second grip tabs respectively extending radially from a longitudinally extending central axis of the inner sleeve and the outer sleeve. Movement of the first grip tab and the second grip tab towards each other rotates the inner sleeve relative to the outer sleeve, and causes the first cleat and the second cleat to rotate towards each other to engage the first and second ends of the spring clip and to enable the spring clip to be removed from an assembled nut plate.
