Fastener is a kind of widely used mechanical parts used for fastening connection

Fastener is a kind of widely used mechanical parts used for fastening connection. Fasteners, industry widely used, including energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, mold, hydraulic, and so on, in all kinds of machinery, equipment, vehicles, ships, railways, Bridges, buildings, structures, tools, instruments, chemical industry, instrument and apparatus, such as the above, you can see all kinds of fasteners, is the most widely used mechanical components. It is characterized by a wide variety of specifications, performance and use of different, and standardization, serialization, universalization of the degree is also extremely high. Therefore, some people have national standards of fasteners known as standard fasteners, or referred to as standard parts.

In all kinds of machinery, equipment, vehicles, ships, railways, Bridges, buildings, structures, tools, instruments, meters and supplies, all kinds of fasteners can be seen above. It is characterized by a variety of specifications, performance and use of different, and standardization, serialization, universalization of the species is also extremely high. Therefore, some people have national standards for a class of fasteners called standard fasteners, or referred to as standard parts. Fasteners are the most widely used mechanical base parts. A large number of Chinese fastener products are exported to other countries in the world, and the fastener products from other countries are also pouring into the Chinese market. As one of the products with large import and export volume in China, the realization of fastener in line with international standards is of great practical and strategic significance for promoting Chinese fastener enterprises to enter the world and promoting fastener enterprises to fully participate in international cooperation and competition. Due to 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.
