Abstract
A sealed attachment fastener assembly with a receiving member and a cap that can be inserted into an opening in a work piece and fixed therein from only one side of the work piece. A portion of the fastener assembly on the blind side of the work piece is collapsible into a flange. In addition, another portion of the fastener assembly is contemporaneously radially expandable within the opening of the work piece to at least rotationally secure the fastener assembly with respect to the work piece. The radial expansion will result in a high interference fit of the fastener in the work piece, which may enhance the fatigue of the installation. A cap completes the fastener assembly to substantially prevent fluid from leaking through the fastener assembly opening. The cap can be assembled with the receiving member after the internal threads within the receiving member have been machined.
