ABSTRACT:
This invention describes a system and method for precisely locating a combined sleeve bolt in an opening located in a plurality of materials adapted to be connected together. The adjustable nut is constructed in two parts and rotatably attached to each other. The first part contains an internal thread for accepting one end of the sleeve bolt and a bearing surface for bearing only on one end of the projecting outer sleeve. The second portion of the nut has a greater diameter for bearing against the bottommost portion of the materials adapted to be connected together. The two portions of the nut being independently adjustable allow the sleeve bolt to be positioned within the hole regardless of any variations in the length of the sleeve. Once the desired position is achieved, the two portions are locked together, preferably by a set screw, and the tapered bolt is pulled into the hole while the adjustable nut holds the sleeve in the desired and pre-adjusted position.
