The global fastener profession mainly provides commodities for electronics, cars, construction and maintenance. China is a country with more exports of stainless steel fasteners, and the quality of fasteners will restrict the development of fastener profession in China.

In 2007, China exported 2.57 million tons of stainless steel rivet nut columns, accounting for 48.95% of the output value of the year. However, the stainless steel rivet nut columns exported by China are still dominated by fasteners with medium and low strength, and the export order is relatively disordered. The export volume is growing too fast. At the time of export, there is too much convergence with the export countries, and there are few goods with low prices and high added value. Then, some anti-dumping and other trade conflicts are often triggered. If the stainless steel rivet nut column of a certain product needs to be installed outside, but the inner space is too small to allow the ram of the sub riveter to enter for rivet pressing and the method of sprouting cannot meet the strength requirements, then both rivet pressing and rivet expansion are not feasible. Pull rivet must be used. It is applicable to the fastening field of plates and pipes (0.5MM-6MM) of various thicknesses. The stainless steel rivet nut can be riveted once with pneumatic or manual rivet gun, which is convenient and firm; It replaces the traditional welding nut and makes up for the defects of thin metal sheet, thin pipe welding fusibility, welding nut irregularity, etc.

Stainless steel rivet nuts are mainly used in the connection of non structural load-bearing bolts, such as the connection of interior trim parts such as rail buses, highway buses, ships and berths. The improved rivet nuts that can prevent spinning are more excellent than aircraft bracket nuts, which have the advantages of lighter weight, no need to rivet the bracket nuts in advance, and no operating space on the back of the base material can still be used. The car industry is a big Z user, The demand accounts for 23.2% of the total sales volume of stainless steel rivet nuts; The second is repair industry malls and construction industry, accounting for about 20% of the total sales of stainless steel rivet nuts; The third is the electronics industry, accounting for 16.6% of the total sales of stainless steel rivet nuts. In recent years, the ratio between the import unit price and the export unit price of stainless steel rivet nut columns in China has become increasingly large. The ratio has exceeded 8 times in the past two years. In 2007, we used 56.95% of the export earnings of stainless steel rivet nuts and imported only 6.81% of the export volume of stainless steel rivet nuts. It can be seen that China's stainless steel rivet nut industry is still a medium career, large but not strong, and is far away from the developed countries in the United States, Japan and Europe.

With the continuous promotion of the process of China's rejuvenation of the equipment manufacturing industry, the speed of industrial upgrading is accelerating, and the integration of China's stainless steel rivet nut column occupation with the world's economy is accelerating, which has put forward higher and higher requirements for the quality of goods and the level of skills of China's stainless steel rivet nut column occupation. Whether the stainless steel rivet nut column occupation can continuously improve its overall level is not only related to the shortening of Chinese cars The overall distance between serious skill allocation and foreign advanced level is also related to the development level of the entire national economy, including people's life. During this period, the car industry is the largest user of Z, with the demand accounting for 23.2% of the total sales volume of stainless steel rivet nuts; The second is repair industry malls and construction industry, accounting for about 20% of the total sales of stainless steel rivet nuts; The third is the electronics industry, accounting for 16.6% of the total sales of stainless steel rivet nuts.
