FIELD: the invention refers to constructions of fastening articles and may be used at assembling thread junctions in machine building. ^ SUBSTANCE: the stud has thread part of a larger and a smaller diameter on the opposite end faces, a collar, a hexahedron, a cylindrical part. At that the hexahedron is placed between the cylindrical part and the thread part of the smaller diameter. As a result the assembling and disassembling of thread junctions including difficult places difficult of access. At that there is no need in special instruments. ^ EFFECT: makes it easier to assemble and to disassemble constructions. ^ 1 dwg |
