    摘要: Fastening art with double nuts for a dual-threaded screw structure is provided, in which loosening is not created even if the structure is subjected to vibration. A spring washer is caused to intervene between the nuts, when double nuts of an inner nut and an outer nut are screwed onto a thread portion on which dual-threaded screw is formed. Only by tightening the outer nut, also the inner nut is tightened and the spring washer is compressed. Both axial force for clamping the fastened member and axial force between the nuts can be secured with the spring washer, so that loosening does not occur easily.

    摘要: The present disclosure provides an anti-loosening screw pair and an anti-loosening screw component. The screw pair includes a first screw component provided with a first screw thread and a second screw component whose outer wall surface is provided with a second screw thread. The first and second screw components are in threaded connection. In a direction of the first screw component being screwed into the second screw component, sides of the first and second screw threads pressing against each other are formed into force-bearing fitting faces respectively, and opposite sides thereof are formed into non-force-bearing fitting regions respectively. At least one of the force-bearing fitting faces and the non-force-bearing fitting regions of the first and the second screw components is provided with a stopper so as to prevent radial displacement between the first and the second screw components.

    摘要: A bolt includes a head portion and a shaft portion. The shaft portion includes an ordinary screw portion that meshes with a nut, and a guide screw portion that is provided on a distal end side of the ordinary screw portion and has a screw thread having a diameter smaller than that of a screw thread of the ordinary screw portion. A protective portion having a diameter larger than a minor diameter of the ordinary screw portion is formed continuously from the guide screw portion at a distal end of the guide screw portion. A pressure flank surface is formed at a distal end of the screw thread of the guide screw portion, but a clearance flank surface is not formed thereat.

    摘要: The bolts of this invention have been provided with the various means for preventing torque transmission to the bolt head when the nut is being tightened, thereby eliminating the need to hold it by a wrench while the nut is being tightened. A nut with a helical or similar cut is provided in order to assure more even distribution of stress among its thread coils. A few different flexible bolts are provided for assembling misaligned flanges and other misaligned connections. Lastly fasteners comprising very strong and light synthetic fiber string with a simple hoist-like assembly on one end and a round stopper-head on the other have been provided, not using the thread at all, to replace the heaviest, longest and most expensive bolts and nuts used on large pipes and pressure vessels or in applications where weight reduction is important.

    摘要: A screw connector includes a first connector with a first lumen and an outside thread, and a second connector with an elastically deformable nut and an inside thread. The outside thread has a first formation and the nut has a second formation, the second formation is a recess in the base of the nut, and the inside thread and the outside thread are configured for mutual connection. The nut is configured for deformation by the first formation in a first angle-of-rotation range without the first formation engaging in the recess, and the inside thread, the outside thread, the first formation, and the recess are configured for engaging the first formation when the inside and outside threads are connected in a second angle-of-rotation range. The screw connector has a half-open sterilization position in the second angle-of-rotation range. In another range, the screw connector may be tightened to be gas-tight and/or liquid-tight.

    摘要: A threaded fastener is provided in which a head bearing surface can be in full intimate contact with a counterpart. The threaded fastener is provided with a head (10), and a screw shank (20) extending from the head (10). The screw shank (20) is provided with a parallel thread portion (22) having a complete screw thread formed therein, a neck portion (24) having no screw thread, a transition thread portion (26) having an incomplete screw thread formed to extend from the parallel thread portion (22) toward the neck portion (24) with its root diameter being the same as that of the complete screw thread and with its thread height gradually becoming lower to reach the neck portion, and an underneck rounded portion (28) formed in a corner angle portion between the neck portion (24) and a head bearing surface (11), wherein the neck portion (24) is work hardened with its diameter being narrowed from a root diameter of the parallel thread portion (22).
