Zusammenfassung:The invention discloses a high-strength fastening bolt. The high-strength fastening bolt comprises a bolt head and a bolt rod, wherein a metal threaded groove is formed in the connecting position of the bolt head and the bolt rod, a threaded section is connected to the right end of the bolt rod, a transition rod is arranged in the connecting position of the threaded section and the bolt rod, and a screw tap is arranged at the tail end of the threaded section. The high-strength fastening bolt has the advantages that the outer diameter of the section of the bolt rod and the width of the bolt head of a T-shaped structure are consistent, the strength of the connecting position of the bolt head and the bolt rod is higher, and breakage between the bolt head and the bolt rod caused by external force is not prone to happening. The high-strength fastening bolt is provided with a cross-shaped angular groove which is located in the center of the bolt head, so that during hanging assembly, the placement position of the bolt head of the T-shaped structure can be judged through the cross-shaped angular groove, and then the assembly time is saved. A thread of the threaded section is a full-tooth-type thread, so that the contact area during screwing of the thread is larger, and therefore the good fastening performance of the contact surface is guaranteed.
