Abstract
A tubular stem (14) at one end of a nut mount (10) is inserted into an opening (O) in a wall (W) and is expanded to connect it to the wall (W). An annular collar or space (16) contacts the wall (W) where it immediately surrounds the opening (O). A clip-on nut (12) is clipped onto a nut receptor (18) that is endwise outwardly of the collar (16). A pushing movement on the clip-on nut (12) moves catch tabs (54, 56) past diametrically opposite edge portions (30, 32) of the nut receptor (18), placing them into positions below the edge portions (30, 32) of the nut receptor (18). When the catches (54, 56) are so positioned, they hold the clip-on nut (12) on the nut receptor (18). The clip-on nut (12) may be a sealed nut. If so, catch tabs (54, 56) are positioned so that when they engage underneath portions of the edge portions (30, 32) of the nut receptor, a seal ring at the base of the clip-on nut (12) is compressed. This compressing of the seal ring (48) causes the clip-on nut to be sealed prior to connection of a bolt to the clip-on nut (12).
