Abstract: A releasable quick-coupling fastener assembly includes a backing sheet (22) having a number of apertured ovaloid bosses (24, 76-90) each presenting a resilient inboard wall structure (108) and resilient inner connective walls (110 and 112) from which depend inwardly extending lip members (118 and 120). The assembly further includes a threaded member (20) having a head (26) and a helically flighted shank (38) for insertion within a boss aperture (106) through a straight application of force by which the shank thread structure (40-54) deformably engages the lip members (118 and 120). The threaded member (20) and be released from engagement with the boss (e.g., 24) through counterclockwise rotation.
