Abstract: A tool and method for threading a stud into a workpiece. The tool has a shaft and a nosepiece which is threaded onto the shaft. The nosepiece has a set of threads which engage the threads of a stud to be inserted into a workpiece. When the nosepiece has been threaded far enough onto the end of the stud for the end of the shaft to contact the end of the stud, the engagement of the stud by both the nosepiece and the shaft rotationally latches the tool to the stud. The tool can then be rotated in the insertion direction to cause the stud to be threaded into a workpiece. Rotation of the shaft in the withdrawal direction causes the end of the shaft to disengage from the end of the stud, thereby removing the rotational latch between the tool and the stud so that further rotation of the tool in the withdrawal direction causes the nosepiece to be threaded off the end of the stud without rotation of the stud in the withdrawal direction.
