In one aspect of the disclosure, an article for filling an opening in an object includes a plug having a body, a first flange, and a second flange. The plug has a trailing end. The first flange is in contact with the body and extends away from the body. The second flange is in contact with the first flange and extends away from the first flange and the body. The second flange is configured to deform toward the body upon installation of the plug into the opening. This deformation of the second flange rotationally and translationally secures the plug in the opening and consolidates the plug in the opening.
