AUTOMATIC STUD DRIVING TOOL HAVING COLLARLESS RETENTION MECHANISM FOR DRIVEN HEAD

摘要

An automatic stud driving tool having greater concentricity and reduced run-out includes a cylindrical hollow body; a carriage disposed within the body including jaws for selectively gripping a stud; a driven head rotatable within the body and selectively engageable with the carriage; a snap ring assembly; and an annular retaining groove located on the inside of the hollow body. The driven head, located partially within the hollow body, is retained within the body by inserting the snap ring assembly into the retaining groove.
