What is thread rolling?

Thread rolling is a metal forging process that forms threads into the mirror image of a roller die. The process is different from metal cutting, grinding, and chasing because it does not remove any metal from the workpiece. Instead, thread rolling uses hardened steel dies to displace and mold ductile metals. The high-pressure process physically changes the properties of rolled metal parts to make the base part and the threads harder and stronger.
