Center tab staking is often used to fasten thin sheet metal parts. The purpose of this paper is to point out that destruction behavior at the fastening portion is dominated by the folding direction of the tab. The results may be summarized as follows : (1) In fastening the lap joints, a tab is bent in the opposite direction of the loading direction. The lap joint is folded once a tab has invariably occured unbending destruction at the root of the tab. For the improvement of joint strength, as far as conditions permit, to increase the tab width and/or increase the number of tabs to prevent concentration of the load is required. (2) The folding direction of the tab is the same as that of loading is brought into bending destruction at the bridge of the slotted hole. Therefore, to make the best of a wide counterpart sheet, it is especially important to demand the same strength as that found in the former joint types, and to choose the bridge of the slotted hole realizing that more than the tab wide is needed.
