Thread Rollers (also known as thread rolling machines) are used to form threads on fasteners like screws and bolts through a cold forming process. By compressing the material between dies, they create precise, durable threads without cutting. Commonly used in automotive, aerospace, and manufacturing industries, thread rollers improve production speed, consistency, and component strength.
