An inexpensive and reliable floating fastener is provided by manufacturing an integrated nutplate into the backside of the interior structural member. A retention clip engages the nutplate to capture the nut while allowing the nut to float. The integrated nutplate roughly aligns the floating nut to the axial through-hole in the structural member and provides the torque resistance required to drive the screw into the nut. The retention clip holds the nut in place and provides the axial resistance required for the lead chamfer of the screw to engage the nut and resist the axial loading on the screw during installation. The nutplate is designed to facilitate cost-effective manufacturing. The per hole cost of the integrated floating-fastener is approximately 30% of the cost of the industry standard riveted floating fastener.
