Due to China's late understanding of the important position of automotive fasteners in auto parts, and the lack of investment for a long time, the whole industry has poor foundation, weak foundation and weak strength. Especially with the improvement of the level of the main engine in China, the bottleneck phenomenon of automobile fastener lagging behind the main engine is increasingly apparent. How to reverse the disorder of domestic automobile fastener industry development is the main problem facing the industry.
Fasteners in the market, also known as standard parts, is the general term of a class of mechanical parts used when two or more parts or components are firmly connected into a whole. It is widely used in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies. At present, with the development of China's manufacturing industry, fastener, as one of the products with large import and export volume, is of great practical and strategic significance to promote Chinese fastener enterprises to go to the world and promote fastener enterprises to fully participate in international cooperation and competition. The specification, size, tolerance, weight, performance, surface condition, marking method of each specific fastener product, as well as the specific requirements of acceptance inspection, marking and packaging, are specified in several national industry standards, such as British system, German system and American system.
Automotive fasteners as the main basic products of automobile manufacturing industry, the development of automobile industry also puts forward higher requirements for fastener products. At present, the supply of domestic ordinary standard automotive fasteners has always exceeded the demand, while the supply of high-grade fasteners such as high-temperature, special-shaped, titanium plastic composite, special performance automotive fasteners is in short supply, and they have to rely on imports. With the improvement of national industrialization level and technical progress, the use of high strength fasteners is gradually increasing.
