A barrel nut fastener apparatus that includes a nut loosely retained in a prescribed position by a retainer that is adapted to be slidably received in a cylindrical bore formed in a panel. The nut is carried loosely on a seat formed in the retainer and is positioned to threadedly receive a bolt projecting through aligned transverse holes in both the panel and the retainer. A spring is interposed between the nut and the seat, to bias the nut outwardly to a position where a cylindrical extension of the nut projects outwardly into engagement with the panel's transverse hole. This ensures that the fastener apparatus remains in its desired position within the panel's cylindrical hole for proper engagement by a bolt. |
