    • 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.
    • 具有接收构件和盖子的密封附接紧固件组件,其可以插入到工件中的开口中并且仅从工件的一侧固定在其中。 紧固件组件在工件的盲侧上的一部分可折叠到凸缘中。 此外,紧固件组件的另一部分同时在工件的开口内可径向扩张,以至少将紧固件组件相对于工件旋转固定。 径向膨胀将导致紧固件在工件中的高过盈配合,这可能增强安装的疲劳。 盖完成紧固件组件以基本上防止流体通过紧固件组件开口泄漏。 在接收构件中的内螺纹被加工之后,盖可以与接收构件组装。
