Below is a list of Cold Headed Fasteners manufacturers from Franklin Park, Illinois. Cold headed fasteners are joining mechanisms used in a variety of industries that are typically formed using the cold heading process. While traditional metalworking uses heat or cutting to adjust the shape of a metal blank, cold forming or cold working uses high pressure from a hydraulic press or ram to force a piece of metal into a pre-formed die. The force exceeds the elastic properties of the material in order to deform it into the desired shape.
