Patent ID: 8398347

Claim:
A fastened structural assembly, comprising: an exterior structural member having a first axial through-hole, comprising: an interior structural member having a second axial through-hole larger than said first axial through-hole and an integrally-formed nutplate on the backside of the interior structural member near the second axial through-hole, said exterior structural member positioned over the front side of the interior structural member to align the first axial through-hole to the lancer second axial through-hole, said nutplate comprising first and second substantially parallel rails on opposite sides of the second axial-through hole, each rail having a pair of through-holes substantially perpendicular to the second axial through-hole, said interior structural member extending laterally away from the nutplate on at least one side of the first or second rails; a nut including a threaded barrel and a base positioned between the first and second rails on the backside of the interior structural member; a U-shaped retention clip inserted through said pair of through-holes in said rail around the threaded barrel and extended through the pair of through-holes in the other said rail so that the nut is captured by the nutplate and the U-shaped retention clip but allowed to float; and a screw driven through said first and second axial through-holes so that a lead chamfer on the screw aligns the nut's threaded barrel and the screw, said nut base engaging said clip which resists an axial load placed on the screw and engaging said nutplate's first and second rails which resist a torque placed on the screw so that said screw is fastened into said threaded barrel by the applied torque.
