US Patent 11448251 Bolt connector

An object of the present invention is to provide a bolt connector that enables a bolt to be inserted into a high nut, and is capable of easily maintaining a connection state between the bolt and the nut. The bolt connector connects two bolts and is configured by: a high nut that has a female screw portion; and a spring that is partially inserted into the female screw portion. The female screw portion is formed having a larger diameter than an outer diameter of the bolt. The spring is formed into a shape in which the spring is in contact with threads of the female screw portion and a male screw portion of the bolt, in a state in which the bolt or the high nut is rotated and fastened.
