Specifically, first, the fastener industry and the enterprise itself are not accurate enough as an important part of the accessory industry. Second, there is a lack of perfect industry standards. In other words, there is a long-standing battle between the host companies and the host companies. The state of the pattern. This is the crux of our fastener industry that has never been able to break through international barriers and rush out of the world. It is also the biggest obstacle for us to lose to foreign brands.

Domestic fasteners have their own role positioning

The domestic fastener companies have not been very clear about their own positioning, blind production, lack of matching and cooperation with the host enterprises. It can be said that the products of most fastener enterprises in China are only mass-produced according to the unified standard. They do not care whether their products can meet the matching of host products on the market, and they are pursuing their own factory quantities, so they are fastened. The pieces become "universal" fasteners, but the mechanical stability of the host application is difficult to guarantee.

Compared with foreign brand products, what we lack is “specialism” and “dedication”. When it comes to this issue, I very much agree with the OEM development model mentioned by Mr. Wang Changjiang, an expert in the construction machinery industry. This concept is developed in the fastener industry. The same applies, that is, the fastener manufacturers mentioned above need to be connected to the host enterprise, which can be one-to-one or even one-to-many.

I think that if we want our fastener industry to compete in the international battlefield, the battle will be the first, "grain and grass" first, that is, the improvement of industry standards, and the alliance with the host enterprises, combined with their own technical quality to win their own piece. country.

There is a gap in the standards of industry products

Comparing domestic industry standards with foreign countries, it is not difficult to find a big gap between the two. As far as the material standards of fasteners are concerned, domestic product standards generally do not specify specific material steel grades, only the chemical composition requirements required for mechanical performance grades. In contrast, individual US standards such as ASTM standards will The material steel grade is specified. Since there is no corresponding grade of steel in China, it cannot be accurately docked with international standards, which will naturally bring certain difficulties to the export. Although some domestic enterprises have begun to realize this, they have developed new steel grades stipulated by foreign fastener standards, but this is only a small step in the process of advancement. International standards need to be promoted and improved throughout the industry.

Note: International fastener products have two sets of relatively independent standard systems of metric and imperial standards. The metric standard is the European standard system, which is based on the international ISO, the European Community EN standard and the French DIN standard. The American standard is the American standard system, which is based on the American Society for Testing and Materials ASTM, the Automotive Engineers Association SAE standard, and the American Fastener Technology Association IFI standard (the British standard is based on ASTM and SAE).
