PURPOSE: A bolt set for assembling a machine product is provided to be applied to bolts of any sizes by replacing a busing because the bolt set is composed of a basic bolt and the busing joined to the basic bolt. CONSTITUTION: A bolt set (100) for assembling a machine product includes a basic bolt (10) and a bushing (60). The basic bolt is composed of a head (20) and a body (30). The busing is joined to the body of the basic bolt. The body includes a sland unit (31) formed under the head; and a screw unit (32) formed under the sland unit. The bushing includes a flange unit (61) whose diameter is larger than the diameter of the head; a cylindrical unit which is formed under the flange unit; a cylindrical hole (70) formed inside the cylindrical unit; and a cylindrical screw unit formed on a portion of the cylindrical hole. The basic bolt is joined to the bolt hole with the same size as the basic bolt after the bushing is joined to the basic bolt. |
