Thin sheet metal parts under low load can be mechanically fastened without the use of fasteners. But there are a number of unclarified points regarding the fastening characteristics. The present report, therefore, aims at presenting basic data on the crushing behavior of lap joints used by lanced tab. The following summarizes the experimental results : (1) The crushing strength is markedly reduced when the joints are used so as to disregard the action direction of the external force and size of the crushable area. (2) In spite of the joint shapes, the crushing strength is took a maximum value within a certain staked force, accordingly, recognized the existence an adquate value of the staking force for the several lap joint. (3) Best strength conditions are achieved when the root of the tab is restrained by the slotted hole edges in the counterpart. (4) From the viewpoint of joint efficiency, this is one of easiest methods for permanently assembling light parts.
