When in use, the rubber ring is sleeved on the outer side of the screw rod. When the screw rod is installed, the rubber ring is located between the nut and the installation surface, preventing the lower end of the nut from squeezing the installation point and causing wear at the installation point. And the wear-resistant strength of the screw is improved through the sprayed wear-resistant layer. The nut and the screw rod are integrally formed to enhance the overall structural strength of the screw.
