A fastener assembly comprises: an insertion-extraction tool comprising a lever with a sleeve passing through one end from a front surface to a back surface and protruding from the back surface, a first ramp that circumscribes about one-half of the sleeve and a second ramp that circumscribes about one-half of the sleeve opposite the first ramp, the first ramp with a ramped surface that faces away from the back surface of the lever and the second ramp with a ramped surface that faces toward the back surface of the lever; and a wedge lock assembly comprising multiple wedges and a captive screw passing there through, the captive screw having a shank that passes through the sleeve of the insertion-extraction tool and a head on the distal end of the shank adjacent to the front surface of the lever of the insertion-extraction tool.
