　　Fastener is a kind of widely used mechanical parts for fastening and connecting. It is widely used in all kinds of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, instruments and supplies. You can see all kinds of fasteners. It is characterized by a wide variety of specifications, different performance and uses, and a high degree of standardization, serialization and generalization. Therefore, some people refer to a kind of fasteners with national standards as standard fasteners, or referred to as standard parts for short.

　　Behind the construction of huge buildings, small fasteners play an indispensable role. Although they are only small participants, they have a vital impact. Because of the importance of convergence, consumers will have more favor of brands in purchasing.

　　Luo Baihui, Secretary General of the International Die Association, said that with the development of China's manufacturing industry, fasteners, as one of the products with large import and export volume in China, have important practical and strategic significance in promoting Chinese fastener enterprises to go to the world and fully participate in international cooperation and competition. As the specifications, dimensions, tolerances, weight, performance, surface conditions, marking methods, acceptance inspection, marking and packaging of each specific fastener product are specified in several national (industry) standards, such as English system, German system and American system.

　　Mechanical industry is one of the main users of fasteners. Due to China's late understanding of the important position of mechanical basic parts in the machinery industry and the long-term lack of investment, the whole industry has a poor foundation, weak foundation and weak strength. Especially with the improvement of the level of China's main engine, the bottleneck phenomenon of mechanical basic parts lagging behind the main engine is increasingly apparent. In recent years, although the state has given some support in technology introduction, technological transformation, scientific research and development, there is still a big gap compared with the current market demand and foreign level, which is embodied in the following aspects: less varieties, low level, unstable quality, high early failure rate and poor reliability.

　　As the main basic parts of the mechanical industry, the development of the mechanical industry also puts forward higher requirements for fastener products. Luo Baihui believes that at present, the supply of domestic common standard fasteners has been oversupplied, while the supply of high-grade fasteners (high temperature, special-shaped, titanium plastic composite, special performance and other fasteners) is in short supply, and they also rely on imports. The State Bureau of machinery has listed "ordinary standard fasteners" as restricted products, and "high strength special-shaped fasteners" as current encouraged products. With the improvement of national industrialization level and technological progress, the use of high-strength fasteners is gradually increasing.

　　It is understood that during the 12th Five Year Plan period, the number of construction machinery products such as loaders, excavators and rollers will reach 6 million, and the annual sales volume will be about 50000. According to the estimation, the annual demand for high-strength fasteners is about 20000-30000 tons. The basic parts represented by fasteners are not only the basic industry of China's equipment manufacturing industry, but also the important foundation of various fields of national economic construction. During the 12th Five Year Plan period, while maintaining part of the cost advantage, the industry must rely on new advantages such as technological progress, quality improvement and product cost performance to achieve sustainable development. It is estimated that the total output of the whole industry will reach 7.5-8 million tons by the end of 2015; under the overall situation of expanding exports, the export products will show a fluctuating growth trend, and the average annual export growth rate is expected to be 8% - 10% during the 12th Five Year Plan period, and the total export of the whole industry will reach 30 billion yuan by 2015.

　　Industry experts said that domestic fastener enterprises should look to the future. "High speed rail", "aerospace", "highway", "airport" and other national key construction projects are providing an opportunity for tight enterprises to move to the high end. Boeing plans to add 3400 aircraft in the next 20 years, and the National Development and Reform Commission has invested 800 billion yuan in the construction of urban rail transit in six cities, according to 36 plans According to the planning of the project city, by 2020, the new operating mileage of urban rail transit will reach 6560 km, and the demand for rail fasteners will reach 5.5-7 billion yuan. These large-scale projects will greatly increase the demand for high-strength fasteners, titanium alloy and other high-end fasteners. It is possible to remove the "low-end" label.
