High-strength wear-resistant bolt with long service life

The utility model belongs to the technical field of bolts, in particular to a high-strength wear-resistant bolt with long service life, which comprises a screw rod and a screw cap, the screw cap is fixedly connected to the upper end face of the screw rod, threads are arranged on the outer wall of the screw rod, a convex ring is fixedly connected to the lower end face of the screw cap, and the convex ring and the screw cap are of an integrated structure. The outer wall of the screw is sleeved with a wear-resistant ring, the bottom of the wear-resistant ring makes contact with a workpiece, so that wear of the bolt is reduced, meanwhile, wear of the bottom of a nut to the outer wall of the workpiece is reduced, the wear-resistant degree is greatly improved, the wear-resistant ring is integrally in an inverted trapezoid shape, and the bottom of the wear-resistant ring is extruded into a plane, so that the contact area of the wear-resistant ring and the workpiece is increased. The connecting firmness of the bolt a
