Advanced bolts are the basis of high-end machinery manufacturing, and their role can be described as a combination of two. The surface bolts only account for a few percent of the machinery industry. In essence, the added value it brings to key components and equipment is much higher.

In the past 10 years, China's bolts have drawn world attention. While surprised by developed countries, they have also allowed them to discover a new type of big market. Multinational companies have come alive.

When domestic bolt companies suddenly felt that the market survived so hard, powerful competitors have blossomed.

In today's bolt market in China, some small and medium-sized bolt companies have manufactured large quantities of common standard parts. They have not really brought core competitiveness to enterprises but are subject to changes in the conditions of raw materials and labor costs. From 4.8 to 6.8 low-strength, or 8.8 to 12.9 high-strength bolts, China's current bolt production technology level will be basically close to the world's advanced level, mainly for ordinary standard parts and low, mid-grade special, special-shaped bolts. Big and cheap.

Summarized as low-grade products flooding the dominant market, a small number of high-grade, high-precision, high-strength bolts still need to be imported, the ratio of product import unit price to export unit price is more than about 6 times.

It can be seen that the bolt industry in China is still a developing industry. It is large but not strong, fat and not strong. It has a wide gap with the United States, Japan, South Korea, and Taiwan, and lacks technical services to solve mechanical fastening solutions. Digitalization of design, manufacturing, and management, and the greening of products and manufacturing processes.

It is understood that the development of China's bolts has been increasingly pressured by resources and the environment. An important way to ease resource constraints is to develop green manufacturing.
