Zusammenfassung:	The utility model discloses a novel locking test bolt, and relates to the technical field of metal workpieces. The bolt comprises a bolt head, a connecting column is fixedly connected to one side of the bolt head, external threads are arranged on the outer side of the connecting column, a guiding structure used for injecting lubricating oil is arranged in the connecting column, the bolt head is communicated with the guiding structure, a detachable sealing piece is fixedly connected to one side of the bolt head, and the sealing piece is fixedly connected to the other side of the bolt head. When the bolt is disassembled, lubricating oil can be poured into the guide structure, the lubricating oil can be guided through the guide structure, so that the lubricating oil permeates into a thread gap so as to lubricate the surface of the connecting column, and then people can disassemble the bolt conveniently; and the sealing element can be operated, so that clamping of the sealing element to the bolt head is cut off,
