Summary: | The utility model discloses a novel bolt which comprises a bolt head and a bolt rod. A polygon groove is formed in a section where the bolt head is far away from the bolt rod, molybdenum disulfide is arranged on the bolt rod, the bolt head is of a hexagonal structure, and the groove is of a triangle structure. The polygon groove is formed in the end face where the bolt head is far away from the bolt rod, when a transverse upper space of the bolt head is not enough, a wrench head which is matched with the polygon groove is longitudinally inserted in the polygon groove, then a transverse handle which stretches out of a wrench is rotated, so that the bolt can be convenient to dismantle. In addition, the molybdenum disulfide is arranged on the bolt rod, so that the molybdenum disulfide not only increases lubrication degree of a screw cap and a screw thread, but also generates a protective layer on the screw thread, prevents the screw thread and the air from being contacted in a large-area mode, and improves corro |
