Beschreibung
Zusammenfassung:	The utility model relates to a dodecagonal high strength flexible bolt, which comprises a dodecagonal bolt head and a screw formed integrally with the bolt head.The front of the screw is equipped with a thread section.The connection parts of the screw with the bolt head and the thread section adopt the arc transition.The external diameter of the screw is smaller than the bottom diameter of the thread of the thread section. According to the utility model, the rigidity of the bolt is lowered and then the stress amplitude suffered by the bolt in a bolt connection of a dynamic load is lowered. The fatigue life of the bolt is prolonged. Meanwhile, the bolt is convenient in installation and high in robustness.
