A one-piece molded plastic reusable internally threaded anchor nut removably insertable in a mounting hole in a workpiece and adapted to receive a screw comprises two sections which are joined together by an integrally formed web or hinge. When the sections are folded together, they define an internally threaded screw-receiving passage and an external releasable locking mechanism for securing the anchor nut in the mounting hole. In one embodiment the portions defining the screw-receiving passage are bifurcated and expand outwardly as the screw is inserted so as to cause the external locking mechanism (i.e., in the form of slots on the exterior of the bifurcations) to engage the edge of the mounting hole in which the nut was previously inserted. In other embodiments, the external locking mechanism (i.e., in the form of manually depressible flexible projections or tabs) operates independently of screw insertion and the anchor nut with the screw already disposed therein is insertable into or removable from the mounting hole when the projections are depressed.

Anchor nut for threaded member

A two-piece molded plastic support assembly for mounting on a wall or door panel of a storage refrigerator or freezer compartment, comprises a grommet member which is insertable into a preformed hole from the front side of the panel and further comprises a support member which is detachably mounted on the grommet member to operatively engage a shelf or drawer or a door handle for the storage compartment. The grommet member has a grommet shank insertable into the hole on the panel's front side (prior to in-situ application of liquid insulating foam to the panel's rear side). The grommet shank comprises a resilient annular grommet flange engageable with the panel's front side to seal the panel hole against foam or air leakage and also comprises releasable exterior locking tabs for engaging the panel's rear side to lock the grommet member in place and to effect sealing action of the grommet flange. The grommet shank also has a blind bore extending axially thereinto from its front end. The support member comprises a support shank which has resiliently flexible tabs thereon which frictionally engage the grommet bore. The support member also comprises a rigid flange which overlies the grommet flange and transfers the load to the panel instead of the grommet.
