Abstract

The present invention discloses a method for working a thread onto a deformed bar for reinforcing concrete.. The method comprises the steps of pressing the deformed bar to a predetermined diameter using a die having thread formations thereon to correspondingly form thread marks on the deformed bar; and rolling the pressed deformed bar to form the final thread.. The method increases the quality and consistency of the final thread.
