A sealed rivetless nut plate which includes a retainer, a nut and a gasket, all retained in a shroud. The nut includes a threaded throughbore for threadably receivin g a fastener as well as either holes or slots which receive corresponding protrusions or dimples on the retainer. Alternatively, the nut (32) can include protrusions or dimples wit h the retainer providing corresponding holes or slots. Regardless, this feature is configur ed to provide a specific amount of x-axis and y-axis floatation. The shroud has a rolled end which keeps the assembly intact. The shroud allows only a nominal amount of movement of the nut in the vertical axis. Before installation, a mandrel is engaged in the assembly. During installation, the mandrel is pulled out, causing a tubular portion of the retainer to expand, against a workpiece, thereby securing the sealed rivetless nut plate in position.</SDO AB>
