Abstract: PURPOSE: A method for forming fiber flow for bolt is provided to obtain bolts with an excellent torsional rigidity and increased coupling force and durability by suppressing plastic deformation and strain hardening at the head core of mold during cold forging. CONSTITUTION: A method for forming a bolt(10) includes a rod wire extrusion step; a cold forging step for cold forging the material at a temperature lower than a re-crystallization temperature of the material so as to improve physical and mechanical characteristics of the material; and a cold rolling step for forming a screw. In the cold forging step, head core of the mold is formed flat so as to form the upper end of a bolt head(12) flat. A heat treatment process constituted by an annealing process which is performed at a temperature of 510 to 580 Deg.C for 100 to 180 minutes, is added after completion of the cold rolling step, so as to thereby remove residual stress. A fiber flow is distributed all over the bolt head and formed near vertical with respect to a torsional torque direction(30), in such a manner that the bolt head is provided with an excellent torsional rigidity.
