Fastener material standards and a brief description of fastener product standards

To create a reputable screw brand, fastener companies need to develop a professional attitude in the technical industry and produce specialized, sophisticated and special products. The OEM development model is also applicable to the development of the hardware fastener industry. Hardware fastener manufacturers need to associate host companies, which can be one-to-one or even one-to-many supporting production. In line with domestic and foreign market demand, gradually expand production capacity and develop emerging markets. The strategy of going global is inseparable from the implementation of standardization. Standard fasteners are convenient for matching and connect with other common parts and components to play a fastening role. A brief description of the fastener material standards and fastener product standards is as follows:

Fastener material standards:

There is a certain gap between domestic hardware fastener industry standards and international standards. As far as the material standards for hardware fasteners are concerned, domestic product standards generally do not specify specific material steel types, but only specify the chemical composition requirements required by the mechanical performance level. In contrast, individual American standards such as ASTM standards will Specific materials and steel grades shall be specified. Since there is no corresponding steel grade in China, it cannot be accurately connected with international standards, which will naturally bring certain difficulties to export. Although some domestic companies have begun to realize this and have developed new steel grades specified by foreign fastener standards, this is only a small step in the progress, and international standards need to be promoted and improved throughout the industry.

Fastener product standards:

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