ABSTRACT:
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. The nut and seat have conforming cross-shaped configurations such that the compressive force of their engagement is distributed over a relatively large area, thereby substantially reducing the possibility of the nut being deformed if the bolt is overtightened.
