Abstract: PURPOSE: A nail with an excellent gripping force and excellent workability and a construction method thereof is provided to improve the gripping force at an end portion due to the blowing portion of an expansion portion during nail construction. CONSTITUTION: A nail with an excellent gripping force comprises a support portion(100) and a head portion. The support portion is separated a long support portion and a front support portion and is connected with a coupler. The head portion comprises a fixed body(210), an expansion portion(230), a front case(240), and a fixture(250). The fixed body comprises an outer taper and an inner taper. The expansion portion is expanded in order to prevent the pullout of the nail by a fixed wedge inserted around. The front support portion is fixed on the fixed body and includes a stopper(241) protruded to an internal space. The fixture is fixed on one side of the support portion and includes a female screw penetrated by a bolt in order to insert a bolt.
