According to data analysis, during the years from 2011 to 2017, the growth rate of China's automobile production and sales slowed down. In 2017, China's automobile production and sales completed 29,015,400 and 28,878,900 units respectively, increasing by 3.195% and 3.04% over the previous year respectively, according to statistics

The data show that China's automotive fastener product varieties meet the rate has reached more than 60%. The domestic market satisfaction rate has reached more than 70%, the production capacity of general low-end products has greatly exceeded the market demand, and as labor-intensive and raw material intensive automotive fasteners, China is also increasing the intensity of technology research and development and the introduction of equipment in various aspects. However, compared with the advanced technical level of screws and fasteners in foreign countries, the comprehensive technical level of Chinese fasteners is slightly behind. The screws used in some key parts of automobiles, such as cylinder head bolts, connecting rod bolts and tire bolts, are due to material and technical reasons. Or how to import products in China, although the domestic technology level also constantly improve, also synchronized to this research, but for the moment, our country has yet to mass production, can't satisfy the demand of the market, the competitiveness of China's automobile fasteners can have so much to ascend, mainly is the BYD auto brands, such as the Great Wall motors. The development of the automotive industry for fastener products also put forward higher requirements, Stone screw manufacturers think. In the future, automotive fasteners will present the following trends:
