A screwing apparatus includes a support member having a horizontal support surface. A single urging member has an urging surface opposed to the support surface. The urging surface is set parallel to the support surface. A driving mechanism is configured to drive at least one of the support member and the urging member to move to change the distance between the support member and the urging member. Driver bits have the tip ends opposed to the support surface, respectively. The driver bits are driven to move toward and away from the urging surface.
