A gripping and feeding device includes a pair of arms having one end for gripping and feeding the fasteners toward the nose piece step by step. The arms each includes a shoe for engaging with the fasteners, and a holder for holding and supporting the shoe. An actuating device is slidably engaged with the arms, the actuating device includes two actuators for selectively moving the arms away from each other, and two blocks for selectively moving the arms toward each other.
