Fasteners, commonly known as screws and nuts, are basic mechanical components, hailed as the 'rice of industry'. They can be found in everything from space shuttles, cars, and machinery to tables and chairs. This industry is a labor-intensive, capital-intensive, and high-tech strategic sector, which is highly valued by countries around the world. After years of development, China has become the largest fastener producer in the world. It is reported that there are nearly 10,000 fastener production and trade enterprises in China, employing over a million people, contributing significantly to employment. The carbon steel fasteners produced domestically are mainly used in the automotive industry, electronic products, electronic equipment, machinery, construction, and general industrial applications. Looking at the national production areas, the fastener industries in Wenzhou, Yongnian, and Haiyan are the most developed and distinctive.

Disadvantages: In recent years, the government's attention and support for fastener industries, which are highly polluting and energy-consuming, have been relatively weak. Many fastener companies have been forced to relocate, leading to a significant decrease in the number of fastener enterprises.

Advantages: The fastener industry started relatively early among the three major industrial bases. Years of accumulation, along with a series of difficulties encountered in recent years, have made fastener companies realize the importance of Brand and image.
