Fasteners include: bolts, studs, screws, nuts, washers, fasteners, also known as standard parts in the market. It is a kind of mechanical parts used for fastening connection. It is widely used. The characteristics of fasteners are variety, specification, performance and application, and the degree of standardization, serialization and generalization is extremely high. Therefore, some people have already called the national (industry) standard fasteners as standard fasteners, referred to as standard parts. The specifications, dimensions, tolerances, weight, performance, surface, marking each specific method of fastener products, specific requirements and acceptance inspection, marking and packaging items, are respectively specified in several countries (industry) standards, such as the British, German and american.
Fasteners in the market also known as standard parts, is to two or more than two parts (or components) fastening connection, as a whole when the use of a class of mechanical parts of the general term. Fastener is characterized by a variety of specifications, performance and use of different, and standardization, serialization, universal degree of extremely high. Fasteners are the most widely used mechanical basic parts, and they are in great demand. Fasteners are a kind of mechanical parts which are widely used for fastening connection and are widely used. A wide variety of fasteners can be seen on a variety of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, instruments and supplies. Fasteners are used in a performance manner, which can show good performance characteristics, use contribution and value, and be used in corresponding industries.
Fasteners are the most widely used mechanical basic parts. With China's accession to the WTO in 2001, and entered the ranks of international trade powers. Fastener products have been exported to many countries and countries all over the world, and fastener products are also pouring into the Chinese market. Fasteners as China's import and export of a large amount of products with international standards, to promote Chinese fastener enterprises to the world, to promote the fastener enterprises to fully participate in international cooperation and competition, all with significance and important strategic significance. Fasteners are two or more than two parts (or components) fastening connection, as a whole when the use of a class of mechanical parts of the general term. It is also called standard parts in the market.
