ABSTRACT:
Methods and apparatus for securing a tie rod to a shroud support structure are described. One embodiment of the apparatus is a toggle bolt assembly including a toggle bolt body having an upper threaded portion and a lower toggle engaging portion. A toggle is rotatably secured to the toggle bolt body at the lower toggle engaging portion. A crimp nut including a threaded nut portion and a crimp collar is threadedly secured to the upper threaded portion of the toggle bolt body. Such toggle bolt assembly also includes a sleeve sized to have at least a portion of the toggle bolt body and the toggle located therein. The sleeve has a toggle opening so that the toggle can rotate from a first position in which the toggle is substantially located within the sleeve to a second position in which surface engaging portions of the toggle extend beyond the sleeve. A lower portion of the sleeve has a toggle rotation surface to facilitate rotation of the toggle.
