摘要： A method of cold rolling a thread on a tubular support member of a rotary shouldered thread connection includes obtaining an original root depth of a thread root, cold rolling the thread until a minimum increased root depth tolerance is achieved. The thread may be cold rolled with a wheel tip having an elliptical profile.
