Title: Self-contained fastener device

Abstract: The present invention is for a fastener device used to releasably fasten a first object and a second object. The fastener device is self-contained and includes a unitary housing that is releasably fastened to the first object. The housing has an annular wall that defines an exterior surface, an interior surface, and an upper and lower opening. Within the housing, extending radially inwardly from the interior surface is a housing stop shoulder. A retaining cover is threadingly attached to the housing at the lower end of the housing. The retaining cover is retained within the housing by a retainer ring. The fastener device also includes a threaded stud that is located within the housing. The stud includes an enlarged section which mates with the housing stop shoulder when the fastener is in a fully engaged position. The engagement of the enlarged section and the housing stop shoulder serves to retain the stud within the housing when the fastener is in a fully engaged position. When the fastener is in a disengaged position, the stud is adapted to engage the retaining cover. As the stud is rotated, it ceases engagement with the retaining cover, and the stud is biased upward by a spring until the stud contacts the second object. The stud is again rotated so that the threads on the stud engage the second object, thereby attaching the first object to the second object.
