Case 3285 00 SHEET METAL NUT Abstract of the Disclosure A one-piece sheet metal nut particularly adapted to be clamped against a plastic workpiece to accommodate any cold flow of the plastic under the clamping force without appreciably reducing the tension in the joint thus created. The nut incorporates an inner internally threaded body integrally connected by an upper top wall to an outer body. The lower region of the outer body is frustoconical and adapted to engage a mating frustoconical surface in the plastic with the uppermost extrem- ities of the nut incorporating an axially compressible spring means permitting portions of the sheet metal nut to move longitudinally relative to one another, which, in conjunction with the broad surface contact between frustoconical surfaces, overcomes any cold flow effect.
