FIELD: plastic metal working, namely method for knurling thread on fluted rod. SUBSTANCE: thread is knurled only on one end of fluted rod. In order to realize it before upsetting hot end of rod in such a way that cross section area of knurled thread was at least equal to cross section area of remaining part of rod, ribs and channels of rod are removed. End of rod is subjected to controlled heating beginning from leading zone of flute-free portion of rod and providing temperature increase towards other end of flute-free portion. Fixed fluted rod is pressed-in to movable cylindrical press-mold. Then thread is knurled on upset portion of rod. EFFECT: enhanced efficiency. 2 cl, 3 dwg
