Abstract
The encapsulated nut of the present invention comprises a stove pipe configured encapsulation, having a base portion for entirely encapsulating the exterior surfaces of a conventional nut such as a nut designed to accommodate a half-inch bolt and having a square exterior shape. The encapsulated nut of the present invention also comprises an integral bore which is configured as an elongated cylinder adapted to receive the portion of the bolt that is threaded through the nut and extends beyond the nut. However, the internal diameter of the bore is greater than the external diameter of the threaded bolt and comprises a smooth surface. Thus, the internal wall surface of the bore is not provided with threads, nor is it cut to form threads when the bolt is threaded through the nut of the invention. Furthermore, there is a small gap between the bore internal wall surface and the threads of the bolt, thus permitting the injection of sealant therebetween to improve the seating engagement between the bolt and the encapsulated nut. The bore is enclosed or capped at the end thereof, opposite the nut. This is done by providing a circular disk-shaped cap which is sonically welded to the open end of the bore, opposite the nut. The entire encapsulation, including the base portion, the bore and the cap is, fabricated by an injection molding process.
