Abstract: A load transfer profile for connection of two bodies without preloading uses a horizontal force couple instead of a vertical force couple for maximum efficiency. The load transfer profile includes a series of tapers and/or diameters that create a radial force couple separated by an axial distance. In particular, the load transfer profile includes at least a first horizontal contact and a second horizontal contact, where each contact is a landing shoulder followed by a stop shoulder or a radial protrusion. The first and second horizontal contacts are offset by the axial distance to accommodate a force-determined bending moment such that system structural fatigue capacity is optimized. A lock mechanism assists with resisting axial loads without creating preload stresses and with locking the bodies together.
