摘要： PROBLEM TO BE SOLVED: To provide a bolt capable of maintaining an attitude of the same and fastening the same appropriately without generating trouble in fastening such as seizure even if the bolt is obliquely screwed in a nut. SOLUTION: The bolt includes a head part and a shaft part extending out from the head part. The shaft part includes a first fixed diameter column shaped part, a transition part, a column shaped connecting part, and a second fixed diameter column shaped part. The first fixed diameter column shaped part has a fixed first diameter along an axial direction and has thread ridges of a designated pitch formed on a side surface. The transition part has a tapered shape of which diameter gradually reduces as it separates from the head part along the axial direction, coaxially projects from a tip of the first fixed diameter column shaped part, and has thread ridges of a designated pitch formed on a side surface. The column shaped connecting part has a diameter smaller than the first diameter along the axial direction and coaxially projects from a tip of the transition part. The second fixed diameter column shaped part has a fixed second diameter smaller than the first diameter along the axial direction, coaxially projects from a tip of the column shaped connecting part, and has thread ridges of the designated pitch formed on a side surface.

摘要： PROBLEM TO BE SOLVED: To facilitate fastening of a bolt from an end surface opposite to a welding side end surface while protecting a screw hole from an outside foreign matter by a cover. SOLUTION: A screw part 4b provided with a screw groove on an inner circumferential surface is formed between one end surface of a welding side 10 of a screw hole 4 and an intermediate part, a part 4C having a diameter larger than that of the screw part 4b is formed between the intermediate part and the other end surface 1b, a cover 2 having at least three or more radial slits 2c from a center toward an outer periphery is broken from the slits 2c by inserting a screw, and is stored in the large diameter part 4c, and thereby, a workability is improved without impeding the cover 2 broken when a bolt is fastened from an end surface opposed to one end surface of a welding side while protecting the screw hole 4 from an outside foreign matter by the cover 2 before fastening. Since a tool for fastening a screw from the other end surface opposed to the welding side 1a can be utilized with its state in this structure, the number of parts can be reduced in case of every use.

摘要： PROBLEM TO BE SOLVED: To provide a drive nut which can prevent any exterior of a cargo from being broken, and be easily driven, but not easily torque-driven when it is driven. SOLUTION: A flange 4 with an outer circumferential edge 11 chamfered in an arc is provided on an upper part of a nut body 1 with a female screw formed on an inner circumferential surface thereof, and a plurality of ridge- shaped projecting bars 14 for locking purpose are provided in a perpendicular direction downwardly from a bearing surface 13 of the flange 4 at specified intervals on an outer circumferential surface 12 of the nut body 1. Since no sharp edge is formed on the flange differently from a conventional nut, a packing material of the cargo is not hooked thereby. In addition, the ridge-shaped projecting bar 14 is not deformed, and a high tightening torque can be ensured.
