A barrel nut type fastener (100) is provided for securement within an opening (20) to a panel ("P") by a threaded member ("T") that when rotationally advanced through the barrel nut causes free-ends (14) and (14') of resilient legs (10) and (10') to move away from each other and respectively engage and urge resilient fingers (16) and (16') into contacting engagement with opposite sides of opening (20) with sufficient force to secure fastener (100) to panel, ("P").
