For what purpose is a die used in metalworking?

In metalworking, a die is predominantly used for shaping and forming materials. Specifically, when it comes to forming male threads, a die is a critical tool that allows for the precise creation of external threads on cylindrical objects, such as rods and bolts. The die cuts into the metal as it is turned, removing material to create a helical ridge that enables threads to engage with nuts or other threaded components. This process is essential for producing threaded fasteners that are necessary for connecting various parts in assembly and construction.

While other tools and processes exist for cutting, polishing, or drilling, the specific function of a die directly relates to the formation of threads, making it an indispensable tool in the machining process. Understanding the role of a die in creating male threads highlights its importance in producing components that ensure secure mechanical connections.
