Abstract
A fastener assembly having a receptacle attached to the underside of a first panel aligned with a first hole adapted to receive therein a threaded bolt extending through a second hole in a second panel. The holes are aligned and a spring-biased expandable bushing, associated with the receptacle, extends into the first hole receiving the bolt therethrough. When the bolt is threaded into the receptacle, the nut is drawn up, compressing the spring and biasing the bushing, expanding the same, completely, filling the first hole and providing a firm locking engagement therein.
