Enclosed is a removable fastening assembly (80, 82, 84, 86) that can be secured to and removed from the same side of an opening in an article such as a plate (10) or the like into which an externally threaded member such as a screw ("S") is to be received by compressing opposed spaced-apart contracting means (18, 18', 58, 72) towards each other exposed on the side of the fastener facing away from the article opening (38) to cause a compressible member (16, 16', 56, 68) disposed on the side of the fastener facing towards the opening to contract sufficiently to be received into the opening with at least a portion thereof pressing against opposite sides of the wall of the fastener surrounding the opening with sufficient force to secure the fastener to the article upon release of the compressive force. The fastening assembly is provided with means (24, 24', 42, 44, 48, 76) for engaging the threads of the threaded member and enabling the threaded member to be secured to the fastening assembly and preferably includes a bridging member (12, 12', 12'') that is adapted to bridge across the article opening and has receiving openings disposed on opposite sides of the thread engaging means for receiving the contracting means therethrough.
