  • Patent number: 5624319
    Abstract: A process for production of a two-part cage nut from a single metal plate. The cage nut includes a nut slidably carried on a holding part. The nut includes a base plate having a threaded sleeve. The holding part includes a holding plate having an aperture and a pair of side walls which are bent over the edge of the base plate of the nut. The process production includes stamping the holding part and nut from a single metal plate. The nut is joined to the base plate by a narrow connecting web. The base plate is then bent about the connecting web and positioned over the holding plate between the side walls. The side walls are bent inwardly until they extend over the side edges of the base plate of the nut. The nut is separated from the holding plate by shearing off the now bent over portion of the connecting web. The nut is permitted to slide between boundary tabs on a guide path between the side walls.
