ABSTRACT A fastener arrangement is provided for the clamping together of two objects, such as the adjacent sidewalls of enclosures or the like. The fastener arrangement is used with predetermined aligned openings in the objects to be fastened and is installable from either side of the objects. The fastener arrangement includes a first member insertable through the predetermined aligned openings from either side of the two objects. The first member includes two spaced-apart, facing damping surfaces. Upon insertion of the first member into the installed position, each of the clamping surfaces engages one of the respective sidewalls. After insertion of the first member, the desired clamping force is applied. In a specific embodiment, the first member carries a threaded stud that extends from the side from which it is installed. A nut is assembled onto the stud to apply the clamping force. The dimensions of the predetermined aligned openings and the fastening arrangement are related so that the first member is easily insertable into the opening, but cannot fall through to the other side. Further, the first member does not need to be held in any way and is both self-supporting and self-aligning during installation and clamping. Thus, assembly merely involves the placing of the first member through the aligned opening, whereupon it is self-guiding into the assembled position, and thereafter applying the clamping force. The arrangement is also easily removable and reusable. Additionally, the first member closes off the opening between the two sides. In a specific embodiment, the predetermined opening is generally T-shaped.
