Thread rolling makes use of hardened steel cylindrical dies to shape materials; the dies, imprinted with the thread profile, penetrate the work metal at ultra-high pressures in order to displace and mold it into a mirror-image thread.

For the same reason, rolled threads are often much smoother, and damage resistant during handling than cut threads. Thread rolling changes the mechanical properties of the material by work hardening it, resulting in increased wear and fatigue resistance, as well as enhanced shear, tensile, and yield......

Thread rolling machines are used to produce screws, bolts, and studs. Thread rolling is a cold-form forming operation used to form external screw threads in a blank. During the thread rolling process, a hard die is pressed onto a rotating workpiece (also called a blank) that is attached to the threa......
