An automatic stud driving tool is provided having a carriage, and a set of jaws disposed within the carriage. The jaws and carriage are provided with permanent contours that prevent the jaws from being withdrawn from the carriage when the jaws are open, but which do not prevent such withdrawal when the jaws are closed. The carriage and jaws are rotationally interlocked, and the carriage is capable of axial movement within a body element only when the jaws are closed, and axial movement of the carriage within the body results in the engagement and disengagement of a rotational drive from the carriage. Automatic operation of the tool can be enhanced through the use of a depth gauge.
