PURPOSE: A roller set for correcting wire rods is provided in which a gap between upper and lower rollers is constantly maintained so that positioning bolts are not unlocked by themselves by mounting an appropriate unlocking prevention device on the positioning bolts for preventing generation of defects of wire products. CONSTITUTION: The roller set for correcting wire rods comprises upper and lower roller plates(32,33) on which a plurality of correction rollers(31) are mounted; upper and lower base plates in which the upper and lower roller plates are fixed by bolts(32A,33A); a pair of gap adjusting bolts(36) which control a gap between upper and lower correction rollers by adjusting a vertical distance between the base plates, which are screw linked to the lower base plate by penetrating the lower base plate as they are being screw linked in a direction from the upper surface(34A) of the upper base plate(34) to the lower base plate, and which are inserted into springs at the areas that are positioned between the upper and lower base plates, and inserted into sleeves inserted into cylindrical gears at the areas that are adjacent to the end parts of one side of the gap adjusting bolts(36); and a pair of horizontal adjusting bolts(37) which are contacted with the upper surface(32B) of the upper roller plate(32) by penetrating the flange(34B) as they are being screw linked to a flange(34B) formed on the upper surface(34A) of the upper base plate(34).
