Fasteners are also known on the market as standard parts and are mechanical components that can be mechanically secured or bonded together by two or more elements. It is characterized by a wide variety of specifications, performance purposes vary, and standardization, serialization, the degree of generalization is very high. Fasteners are the most widely used mechanical base pieces and are in great demand. Fasteners can also be used to keep containers (such as bags, boxes) in a closed state, possibly by keeping the opening of the element intact and installing the lid on the container. There are also specially designed components such as a bobbin that does not permanently enclose the container and the user can still open the container without destroying the fastener. Fasteners, fasteners are used for fastening connection and the application of a wide range of mechanical parts, widely used in a variety of machinery, equipment, vehicles, ships, railways, bridges, construction, structure, tools, instruments, chemicals, And supplies above, you can see a wide range of fasteners.
Fasteners are a class of mechanical parts that are used for fastening connections and are widely used. All kinds of fasteners can be seen in all kinds of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, instruments and supplies. It is characterized by a wide variety of specifications, performance purposes vary, and standardization, serialization, generalization of the species is also very high. Therefore, some people have a national standard of a class of fasteners called standard fasteners, or simply referred to as standard parts.
Fasteners are the most widely used mechanical foundation pieces. With China's accession to the WTO in 2001 and entered the ranks of international trade power. China's fasteners a large number of products exported to countries around the world, the world's fastener products are also constantly influx of the Chinese market. Fasteners as one of China's large import and export products, to achieve international standards, to promote China's fastener enterprises to the world, to promote the full participation of fastener enterprises in international cooperation and competition, have a significant practical significance and Strategic significance. Due to the specifications, size, tolerances, weight, performance, surface conditions, marking methods, and inspection, marking and packaging of each specific fastener product, the specific requirements of the project are defined in several national (industry) standards , Such as the British standard, German standard and American standard.
