Abstract: A fastener includes an insert mounted in an oversized elongated aperture of a metal panel. The insert has a tubular body of lesser outside dimension than the aperture, and a hollow interior receiving a threaded stud projecting from the component. The tubular body has a flexible lip engaging the panel and first and second retaining fingers having first shoulders engaging the bottom surface of the panel and second shoulders engaging with opposed parallel extending sidewalls of the aperture to prevent rotation of the tubular body. First and second biasing fingers project from the tubular body to engage opposed curved end walls of the aperture to a bias the tubular body within the aperture as allowed by sliding of the second shoulders along the opposed parallel extending sidewalls. A plurality of ratchet fingers extends into the hollow interior to engage the stud when the stud is installed into the insert.
