A thread rolling machine is a type of metalworking equipment used to form threads on screws, bolts, fasteners, and other cylindrical parts through a cold-forming process. Unlike cutting or grinding, which remove material to create threads, thread rolling displaces and molds the material into the desired thread profile. This process enhances the mechanical properties of the threads, such as strength, surface finish, and fatigue resistance, by compressing the grain structure of the material.

Thread rolling machines are widely used in industries such as automotive, aerospace, construction, and manufacturing due to their efficiency, consistency, and ability to produce high-quality threads at high volumes.
