rolled thread. (b) Grain flow in machined and rolled threads. Unlike machining, which cuts through the grains of the metal, the rolling of threads causes improved strength, because of cold working and favorable grain flow. Figure Threadrolling processes: (a) and (c) reciproing flat dies; (b) tworoller dies.
