Abstract
A shock mounting assembly has a grommet for holding a plate assembled on a weld stud. The grommet is held on the stud by a unitary plastic nut having a sleeve portion extending through the grommet, a central flange portion extending over the end of the grommet and a shaped end portion, such as a hex head. Initially the nut is not provided with threads, the threads being formed on the inner surface of the sleeve portion by being rotated on the stud during assembly.

6. In a mounting assembly including a threaded stud mounted to a base, a grommet for resiliently supporting an element from said stud, and means for retaining said grommet on said stud, the improvement wherein said retaining means comprises a unitary plastic nut having a sleeve portion on one end extending through said grommet and having an internal surface engaging the threads of said stud, a flange portion adjoining said sleeve portion and having an outer diameter to retain said grommet on said stud, and the other end thereof being shaped to engage a tool for rotating said nut on said stud, said stud having an enlarged base portion adapted to be welded to a base, said stud being fully threaded, said sleeve having a length to fully fit over said threaded portion of said stud and engage the base portion thereof, with substantially no compression of said grommet by the flange thereof, said nut further having a radial inward extending shoulder positioned to engage the exposed end of said stud, to further limit tightening of said nut on said stud.
- 7. A nut for a shock mount, comprising a unitary plastic element having a radially extending flange, a sleeve portion extending from said flange to one end of said nut, the portion from said flange to the other end thereof being shaped to receive a tool for turning said nut, said sleeve portion having an unthreaded central hole therein extending from said one end to a radially inward extending shoulder within said nut.
