Abstract
A grommet attached to a top panel captures a stud nut of a panel fastener through a retaining ring held by the grommet. A complimentary stud assembly attaches to a subpanel and receives the stud nut to clamp the panels together. The grommet has a stand-off base that projects axially from a counterbore in the top panel to form a barrier for a gasket. A flared end of the grommet and the standoff base clamp the top panel between them. The retaining ring compressively bears radially against the stud nut to retain it in any desired axial position and maintain axial alignment of the stud nut. The stud nut can draw completely into the top panel. The stud nut has a clear-through bore threaded at one end. A wrenching recess, defined by a hardened insert, occupies the other end of the bore. A plug separates the wrenching recess from the threads. A basket of the stud assembly attaches to the subpanel by rivets. A barrel attaches to the basket through lugs engaged in slots of down turned wings of the basket. Tabs at an extreme end of the barrel crimp into cooperating recesses of a head of the stud to retain the stud with the barrel. The stud extends axially within the barrel for engaging the stud nut. The barrel may press against the nut to restrain undesirable loosening.
