The cold heading process is one of the novel processes for machining less and no cutting metal under pressure. The method is a processing method which utilizes the plastic deformation generated by metal under the action of external force and redistributes and transfers the volume of the metal by means of a die so as to form the required part or blank. The cold heading process is most suitable for producing standard fasteners such as bolts, screws, nuts, rivets, pins, and the like.

The equipment commonly used in the cold heading process is a cold heading machine. The cold header is special equipment which takes a pier as a main part and is specially used for producing fasteners such as rivets, bolts and the like in batches.
