ABSTRACT OF THE DISCLOSURE Immediately behind a tap of an automatic threading machine to which nuts or like pieces are fed in succession, is a straight portion of a cast-off sheet coaxial with the tap and which is followed by an inclined portion including an obtuse angle with the straight portion. Another straight portion paral- lel to the first includes an obtuse angle with the inclined por- tion and guide passages are formed around the inclined portion and the final parallel portion in a head which is rotated to drive the tap. The nuts thus pass over the tap and the cast-off shaft and axial play of the cast-off shaft is minimized.
