ABSTRACT:
A stacked array comprising at least one or more similar or dissimilar metals or composites and having either a tapered bore or a tapered sleeve. A tapered bolt adapted to be inserted into the tapered bore and having a taper that is different from the tapered bore. A method for selecting a greater or lesser taper on the bolt than the taper on the bore depending on the relative strength of the materials forming the stacked array as a means of reducing the installation force of the tapered bolt within the tapered bore.
