Abstract
A cage nut assembly includes a nut and a cage wrapped therearound. The nut has a number of stand-offs or protrusions provided on a lower surface thereof such that the stand-offs are the only part of the nut which are in contact with the cage. The stand-offs reduce the amount of bearing surface interface between the cage and the nut thus reducing the possibility that the two parts will stick to each other after a coating is applied to the mating surface which the cage is welded to. The nut is engaged by a male threaded fastener which is torqued into place and the stand-offs push into the material of the cage causing the cage material to flow out of the way such that the stand-offs embed into the material of the cage without deforming the stand-offs to a flattened condition.
