Radome lap flange hardware with mechanical anti-rotation feature

A radome panel fastener system comprising:

• a first panel comprising an overlap flange having a first hole therein;
• a second panel comprising an underlap flange having a second hole therein, wherein the overlap flange overlaps the second panel and the underlap flange underlaps the first panel in a complementary configuration that enables a top surface of the first panel to align with a top surface of the second panel;
• a first bolt comprising a first shaft having a first annular cavity defined therein, wherein the first shaft is male-threaded in a first configuration, wherein the first annular cavity is female-threaded in a second configuration, and wherein the first shaft passes through the first hole in the first panel;
• a retainer having a second annular cavity defined therein, wherein the second annular cavity is female-threaded in the first configuration, wherein the first shaft is threaded within the second annular cavity, and wherein the retainer includes an anti-rotation mechanism that interacts with the first panel to inhibit rotation of the retainer relative to the first panel;
• and
• a second bolt comprising a second shaft, wherein the second shaft is male-threaded in the second configuration, wherein the second shaft passes through the second hole in the second panel, and wherein the second shaft is threaded within the first annular cavity, thereby attaching the first panel and the second panel.

A radome panel fastener method comprising:

• inserting a first bolt through a first hole in a first panel, wherein the first bolt comprises a first shaft having a first annular cavity defined therein, wherein the first shaft is male-threaded in a first configuration, and wherein the first annular cavity is female-threaded in a second configuration;
• threading the first shaft into a second annular cavity defined within a retainer, wherein the second annular cavity is female-threaded in the first configuration, and wherein the retainer includes an anti-rotation mechanism configured to interact with the first panel to inhibit rotation of the retainer relative to the first panel;
• and
• inserting a second bolt through a second hole in a second panel, wherein the second bolt comprises a second shaft, wherein the second shaft is male-threaded in the second configuration, and wherein first annular cavity is configured to receive the second shaft threaded therein, thereby attaching the first panel and the second panel.
