ABSTRACT:
A fastener assembly having a receptacle attached to the underside of a substructure and extending through a hole within the substructure which are both generally aligned with a panel with a hole adapted to receive a threaded bolt. The hole in the panel has a cylindrical portion. The fastener extends through the panel which is being secured to the substructure and enters the receptacle before engaging a threaded section within the receptacle. The dimensions are sized so that the central section of the fastener engages the central section of the receptacle before the tapered section of the fastener contacts the cylindrical portion of the hole in the panel. Continued rotation of the fastener causes the tapered section on the fastener to enter the cylindrical portion of the hole in the panel, exerting a lateral force on the panel to align the hole in the panel with the bore in the receptacle.
