Bolts: A class of fasteners consisting of a head and a screw (cylindrical body with an outer thread) that are fitted with a nut for fastening the two parts with a pass hole. This form of connection is called Bolt connection. If the nut is removed from the bolt and the two parts can be separated, the bolt connection is a detachable connection. The hexagonal head is the most commonly used, and the general countersunk head is used where the connection is required.
bolts, mechanical parts, cylindrical threaded fasteners with nuts.

Advanced Bolt is the high end of the machine manufacturing of this, its role can be said to be "four two dials the heavy". The output of bolt on the surface only accounted for a few percent of the mechanical industry. In essence, it brings much higher value to key components and equipment.
Over the years, the Chinese bolt in the continuous double-digit growth, the 2012 bolt industry negative growth, year-on-year decline of about 1.5%, the main reason is the lack of market demand, especially the bolts in the international anti-dumping, export sales fell.
The bolt market competes fiercely, moves toward the brand management
In recent 10 years, Chinese bolts have made the world's attention to the pace of development, in the developed countries are surprised, but also let them find a new big market, multinational companies in.
When domestic bolt enterprises suddenly feel that in the market to survive so difficult, strong competitors have been everywhere.
China bolts Market, some small and medium-sized bolts enterprises to make a large number of ordinary standard parts, and did not really bring the core competitiveness of enterprises, but is constrained by raw materials, labor costs and other conditions change. From 4.8 to 6.8 low strength, or 8.8 to 12.9-level high-strength bolts, the Chinese bolt production level will be basically close to the world's advanced level, mainly for ordinary standard parts and low, medium grade special, special-shaped bolts, a large price and cheap.
Summarized as low-grade products flooded the dominant market, high-grade, high-precision, high-strength bolts have a small number of imports still need to import unit price and export unit price ratio of about 6 times times the gap.
Visible, China's bolt industry is still developing industry, "big and not strong," fat but not strong ", with the United States, Japan and South Korea, Taiwan, the gap between the larger, and lack of technical services to solve mechanical fastening programs, the realization of product, design, manufacture and management of digitization, product and manufacturing process of green.
It is understood that the development of Chinese bolts is more and more pressure on resources and environment, and the important way to ease resource constraints is to develop green manufacturing.
The development of bolts, in the future will continue to move towards the direction of brand management, promote the all-round development of Bolt project.
In the product, the high-end products will accelerate the localization of quality research and development, from the design, manufacture, packaging, transportation, use to scrap disposal process, should consider the least waste, the lowest emissions, the highest utilization of resources and environmental impact, so as to optimize the enterprise benefit and social benefit coordination.
In the circulation aspect, explores each kind of value-added service the model, brings the value and the benefit for the customer. From the provision of a single set of bolts to provide mechanical fastening programs, custom services, remote monitoring, etc., the service in the bolt manufacturing enterprise sales revenue will gradually increase in proportion.
Enterprise reorganization is a trend, strategic alliance to develop
At present, the problem of the low industrial concentration of bolt enterprises in China seriously restricts the improvement of China's bolt competitiveness. The opening of the market over the years has not brought about core technology.
In view of the above situation, the reorganization and strategic alliance between enterprises is a big trend. China bolt industry must conform to this trend and trend, strengthen the strategic cooperation between enterprises, improve the overall competitiveness of Chinese bolts.
China's growth in the core technology of bolts is a lack of breakthroughs. At the same time, the survival space of low-grade products are squeezed more and more small, foreign investment through the local enterprises also have a considerable cost advantage, coupled with the advantages of technology brands, began to the original brand market space to enter.
