A mechanical assembly comprising: - a first member, - a second member spaced from the first member, and - a fitting for connecting the first and second members, the fitting comprising: a first mounting portion connected with the first member and having opposing first and second generally planar surfaces and opposing inner and outer ends, a second mounting portion generally angled with respect to the first mounting portion and connected with the second member, the second mounting portion having opposing first and second planar surfaces and opposing inner and outer ends, the second mounting portion inner end being integrally formed with the first mounting portion inner end, and at least one generally elongated boss projecting outwardly from a remainder of the second mounting portion and having an inner end at least generally adjacent to the inner end of the second mounting portion, an opposing outer end spaced from the second mounting portion inner end, a centerline (Lc) extending between the boss inner and outer ends, and an outer surface extending generally between the inner and outer ends of the boss and including an outermost surface section spaced from the second mounting portion first surface by a spacing distance (ds), the spacing distance having a value greater than zero at all points along the centerline, characterized in that the second member and the second mounting portion are connected with each other either directly, the second member having a recess, or through a stiffener of the mechanical assembly, the stiffener being coupled with the second member and having a recess, and in that the at least one boss is disposed within the recess such that the boss outer surface is juxtaposed against at least a substantial portion of an inner surface of the recess. -
