Abstract
A thread-cutting die head includes a die carrier, defining a central axis, for supporting a plurality of thread-cutting dies, a cam plate coaxial with the die carrier including a plurality of cam members for engaging with the plurality of thread-cutting dies, and a locking system including a positioning screw extending through an arcuate slot in the cam plate, a bushing surrounding the positioning screw, and a handle threadably coupled to the positioning screw configured to impart a force against the bushing to press the flange portion of the bushing against the first surface of the cam plate, thereby developing a frictional force between the bushing and the cam plate to lock the rotational position of the cam plate relative to the die carrier.
