| description | A double-square-head round pipe connecting pole bolt comprises a screw rod and further comprises a round pipe, a screw cap, limiting anti-slip teeth and a square-head nut. The screw cap is in the shape of a disk and is connected with the screw rod into a whole, and the limiting anti-slip teeth are arranged at the outer edge of the screw cap. The round pipe is connected between the screw cap and the square-head nut, and the inner wall of the round pipe is fixedly connected with the screw cap and the square-head nut after being in pressure welding with the screw cap and the square-head nut. According to the bolt, a screw, a round pipe stud and the square-head nut are connected together in a pressing welding mode, and compared with a traditional cast or mill-cut structure, the double-square-head round pipe connecting pole bolt has the advantages of being simple in machining, stable in quality and capable of saving cost; the screw, the nut and the round pipe stud are made of different materials, so that the stren |
