摘要： PROBLEM TO BE SOLVED: To provide a fin tube in which even when a thermal conductivity of an inner tube member is small, heat exchange performance is enough improved. SOLUTION: A fin tube 1 includes an inner tube member 2 comprising low thermal conductivity stainless, and an outer tube member 2 comprising high thermal conductivity aluminum. A recessed portion 2a where a tube wall is recessed on the side of a center of the tube is formed in the inner tube member 2. The outer tube member 3 is fixed to or brought into close contact to or with an outer peripheral surface of the inner tube member 2 such that it fills the recessed portion 2a, and includes a fin section 3b formed therein. As a result, heat possessed by EGR gas flowing the neighbourhood of the central portion of a fluid passage 2b is discharged into air of an external fluid through aluminum filled in the recessed portion 2a and through the fin section 3b to effectively cool the EGR gas and hence satisfactorily improve heat exchange performance of the fin tube 1.

摘要： PROBLEM TO BE SOLVED: To provide a means that facilitates manufacturing of a bolt stock by cold forging or the like and that also facilitates forming of a gimlet point thread part on the bolt stock by thread rolling without reducing a life of thread rolling dies.
SOLUTION: In the manufacturing process of a gimlet point bolt 11, the bolt stock 11' having a head 12 and a roughly cylindrical shank is manufactured by cold forging. Successively, in close proximity to the tip end of the shank 13 of the bolt stock 11', there is formed a roughly cylindrical vertical hole 14 opening to the tip end face of the shank. Then, thread rolling is carried out on the outer circumferential face of the shank 13. By plastic deformation, the main thread part 15 with a fixed thread diameter is formed in the portion where no vertical hole 14 is formed in the shank 13, and simultaneously, the gimlet point thread part 16 with the thread diameter diminishing toward the tip end of the shank is formed in the portion where the vertical hole 14 is formed in the shank 13.
