The invention discloses a bolt with a hexagonal threaded end. The bolt comprises a bolt head, a threaded rod connected with the bolt head and a nut in matched connection with the threaded rod. The outer surface of the end of the threaded rod is sleeved with the threaded end in matched connection with the threaded rod, the threaded end is used for fixing the threaded rod when the bolt is screwed up, and the threaded end is of a hexagonal structure. The bolt is provided with the hexagonal end capable of fixing the threaded rod, the defect that when a traditional bolt is fastened, one end needs to be fixed, and the other end needs to be screwed up is avoided, and connecting components can be fastened at one end of the bolt; therefore, time and labor are saved, the labor intensity is lowered, the production efficiency and work efficiency can be improved, and fastening connection between the connecting components can be guaranteed; convenience and practicality are achieved, and the bolt can be suitable for multiple occasions and worthy of wide popularization.
