Cold headed parts are precision components manufactured through a process called cold heading, where metal is shaped at room temperature under high pressure. These parts, such as bolts, nuts, and rivets, exhibit enhanced strength and durability due to work hardening. They often feature precise dimensions and smooth surfaces, requiring minimal post-processing. Common materials include steel, brass, and aluminum, chosen for their malleability and strength. Cold heading allows for the creation of complex geometries, including hexagonal, round, and custom profiles, making these parts widely applicable in industries ranging from automotive to electronics.
