Special-shaped bolts and screws are widely used in mechanical manufacturing. These custom fasteners differ from standard off-the-shelf parts and can be produced with cold heading equipment. What is the principle behind the process? How Cold Heading Works Cold heading forms metal under pressure using tooling designed for the required shape and dimensions. The material undergoes plastic deformation within the tooling. The process is suitable for precision, high-strength components such as bolts, nuts and pins. Forming without the heating used in hot forging helps avoid high-temperature oxidation and discolouration. The Manufacturing Process 1. Design and manufacture the tooling to the component…
