Fastener: It is a general term for a class of mechanical parts used for fastening and connecting a wide range of mechanical parts. It is used to fasten two or more parts (or components) and fasten them together. Fasteners, used in a wide range of industries, including energy, electronics, electrical, mechanical, chemical, metallurgy, mold, hydraulic and other industries, in a variety of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments , chemical, instrumentation and supplies, etc., can see a wide range of fasteners, is the most widely used mechanical basic parts. It is characterized by a wide variety of specifications, different performance uses, and the degree of standardization, serialization, and generalization is also extremely high. Therefore, (forgings: hot forgings, cold extrusions, please contact Hongtengda (HTD) forgings) Some people also refer to the type of fasteners of the existing national standard as standard fasteners, or simply as standard parts.
The machinery industry is one of the main users of fasteners. Due to China's late understanding of the important position of mechanical basic parts in the machinery industry, long-term lack of investment has resulted in poor foundation, weak foundation and weak strength. In particular, with the improvement of the level of Chinese mainframes, the bottleneck of mechanical basic components behind the mainframe has become increasingly apparent. (Qingdao Hongtengda (HTD) Machinery Manufacturing Co., Ltd. specializes in producing all kinds of hot forgings, auto parts, stamping parts). Today, although the state has given certain support in technology introduction, technological transformation, scientific research and development, etc., it is in line with current market demand and Compared with the foreign level, there is still a big gap, which is manifested in: low product variety, low level, unstable quality, high early failure rate and poor reliability. Fasteners as the main basic parts of the machinery industry, the development of the machinery industry, (Hongtengda (HTD) forgings are professional forgings manufacturers, products including all kinds of automotive forgings, mechanical parts forgings, etc.) also put forward higher requirements for fastener products . Domestic common standard fasteners have been oversupplied, while high-end fasteners (high temperature, profiled, titanium-plastic composite, special properties and other fasteners) are in short supply and depend on imports. The National Machinery Bureau listed "general standard fasteners" as restricted development products, and "high-strength shaped fasteners" as current encouraged development products. With the improvement of national industrialization level and technological progress, the use of high-strength fasteners has gradually increased.
A wide variety of fasteners can be found on a variety 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 the degree of standardization, serialization, and generalization is also extremely high. Therefore, some types of fasteners with existing national standards are also referred to as standard fasteners, or simply as standard parts. Fasteners are the most widely used mechanical foundation. As China joined the WTO in 2001 and entered the ranks of international trade powers. (Looking for hot forgings such as claw poles, sliders, rigging, etc., and looking for Hongtengda (HTD) forgings) China's fastener products are exported to the world, and fastener products from all over the world are also pouring into the Chinese market. As one of China's large import and export products, fasteners are in line with international standards, and it is of great practical significance to promote the Chinese fastener enterprises to the world and promote the full participation of fastener enterprises in international cooperation and competition. Strategic significance. Due to the specifications, dimensions, tolerances, weights, performance, surface conditions, marking methods, and specific requirements for acceptance inspection, marking and packaging for each specific fastener product.
