Fasteners are a kind of mechanical parts used for fastening connection and are widely used. Fasteners are widely used in a wide range of industries, 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, instrumentation and supplies, you can see all kinds of fasteners, is the most widely used mechanical base parts. It is characterized by a wide variety of specifications, performance and use of different, and the degree of standardization, serialization, universality is also very high. Therefore, some people have the national standard of a class of fasteners called standard fasteners, or simply referred to as standard parts.

A wide variety of fasteners can be seen on all kinds of machinery, equipment, vehicles, ships, railways, Bridges, buildings, structures, tools, instruments, meters and supplies. It is characterized by a wide variety of specifications, different performance uses, and standardization, serialization, universality of the species degree is also very high. Therefore, some people have the national standard of a class of fasteners called standard fasteners, or simply referred to as standard parts. Fasteners are the most widely used mechanical base parts. Along with our country joined WTO in 2001 and entered international trading big country cavalcade. A large number of our fastener products are exported to all countries in the world, and the fastener products from all countries are constantly pouring into the Chinese market. As one of the products with large import and export volume in China, fasteners are of great practical and strategic significance for promoting Chinese fastener enterprises to go to the world and promoting fastener enterprises to participate in international cooperation and competition. Due to the specifications, dimensions, tolerances, weight, performance, surface conditions, marking methods of each specific fastener product, as well as the specific requirements of acceptance inspection, marking and packaging items.
