The present paper deals with the strength of aluminum thin plate joints using tapping screw. In order to establish a formula of ultimate strength of this joints, loading tests are carried out with varying thickness of aluminum thin plate and tapping screw diameter. This study shows the following results through the above investigations, i) The pull out strength of the tapping screw driving the aluminum thin plate could be determined from the relationship of the tensile strength, thickness, out-of-plane stiffness of aluminum thin plate and the diameter of preset hole, ii) The strength of the single lap-joint which is affected by eccentric loading caused by distance between the axis of connected two aluminum plates could be determined from the relationship of the tensile strength of the aluminum and the thickness of connected two aluminum plates, when the material collapse of the tapping screw and the aluminum plate was not leaded.
