Patent ID: 7921539

Claim:
A method of fastening structural members, comprising: providing a first structural member having a first axial through-hole; providing a second 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 second structural member near the 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; positioning a nut including a threaded barrel and a base between the first and second rails on the backside of the second structural member; inserting a U-shaped retention clip through said pair of through-holes in one said rail around the threaded barrel and extended through the pair of through-holes in the other said rail so that the base is captured by the nutplate and U-shaped retention clip allowing the nut to float; positioning the first structural member over the front side of the second interior structural member to align the first axial through-hole to the larger second axial through-hole; and driving a screw 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.
