Abstract: A plurality of nut inserts (40) and an elongated channel (10) form a gang nut assembly. The channel (10) is formed to include a plurality of longitudinally spaced apart nut receiving openings (28). These openings (28) are partially defined by opposed recesses (24, 26) in flanges (18, 20). The nut insert (40) has a base length (LB) which is smaller than the length (Y) of the opening (28). It also has end walls (44, 46) which diverge apart as they extend upwardly from a base (42). The base (42) is put into registry with the opening (28) and the nut insert (40), is pushed upon, to force it through the opening (28). The sloping outer surfaces of the end walls (44, 46) contact flange edges (30, 32, 34, 36). This causes the end walls (44, 46) to spring together, in response to the push on the nut insert (40), allowing the nut insert (40) to pass through the opening (28).

Abstract: A two-piece molded plastic fastener comprises a hollow body and a pin insertable thereinto. The body has a head and a bore defined by a resiliently deformable grooved bore wall. The pin has a pin head and a serrated pin shank. When fully installed in an aperture in a workpiece (which comprises one or more panels), the serrated pin shank is frictionally engaged with and digs into the resilient grooved bore wall (i.e., is "set"), and the two heads bear against opposite sides of the workpiece. Depending on fastener design, the heads either apply a predetermined pressure on the workpiece (depending on the setting force) or are maintained at a predetermined distance from each other when set. Either the body or pin or both may embody features (such as holes, screw threads, hooks, snap fasteners) which enable objects to be secured thereto. In addition, the pin may have an axial bore therethrough to enable the fastener to serve as a bushing.
