Roll Thread Machines

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 thread rolling machine.With thread rolling, a screw or similar fastener is machined to create external threading. The screw or fastener, without any threading, is pressed with a pre-shaped die. The die cuts away material from the screw's exterior, resulting in the creation of external threading.
