Abstract
An unconventional bolt includes a main body having two heads, and two threaded rods respectively formed at the external surface of each head coaxially with the main body, wherein the cross section of each head has a noncircular shape, and the axial projection of the cross section of the middle of the main body is located in the noncircular axial projection of each head of the main body. The unconventional bolt has a simple structure and a convenient assembly, and can improve the strength and rigidity of the nested profiled components after the connection; and the fastening device using the unconventional bolt can not only support the component but also reinforce it, thus effectively preventing the nested profiled components from transforming.
