Abstract
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 receiving a fastener as well as a base portion which includes either holes or slots which receive corresponding protrusions or dimples on the retainer. Alternatively, the base portion of the nut can include protrusions or dimples with the retainer providing corresponding holes or slots. Regardless, this feature is configured to provide a specific amount of x-axis and y-axis floatation. The shroud is folded under the retainer, thereby keeping 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 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.
