Threading Basics

The screw form as used in manufacturing has two primary functions--to transmit power and motion, as with a lead screw on a machine tool, and as threaded fasteners such as nuts, screws, and bolts. This program examines the many dimensions that make up all threads, such as the major diameter, the minor diameter, the thread pitch, and the thread pitch diameter. You will learn about the various processes that produce external threads, such as manual threading, thread turning, thread chasing, thread milling, and thread rolling. Internal threads, the tapping process, and tapping machines are also extensively explored.
