The nutplate assembly includes an integral liner sleeve to project through the substrate opening when the nutplate assembly is mounted thereon. An installation tool includes a tapered nose in combination with a pulling mandrel to pull and separate a fixture pin from the nutplate assembly while flaring a leading edge of the liner sleeve to lock the nutplate assembly in place.
