A fastener assembly for attaching a cover to a panel includes a stud assembly mounted on the cover and having a stud extending through an opening formed in the cover. The stud has a shank portion which extends through the opening in the cover, a head portion provided on an upper end of the shank portion, and a cross pin provided on a lower end of the shank portion. A grommet is secured to the cover within the opening of the cover for attaching the stud to the cover. The fastener assembly further includes a receptacle assembly including a receptacle barrel having a cylindrical wall with an interior surface having female threads formed thereon. The receptacle assembly further includes an insert having a cylindrical body with an exterior surface having male threads formed thereon. A helix is disposed between the receptacle barrel and the insert, the helix being fabricated from wire-like material and having alternating large and small diameter loops extending along the length of the helix. When releasably attaching the stud assembly to the receptacle assembly, the helix prevents the axial movement of the insert with respect to the barrel. Preferably, the helix has a diamond-shaped cross section which defines, for each coil of the helix, opposite, pointed side edges which are received within grooves constituting the female threads of the barrel and the male threads of the insert.
