Dual-driven By Technological Iteration And Demand Upgrading, The Industry Landscape Of Steel Coarse-thread Round-head Screws Is Undergoing A Reshaping.

As a fundamental component in the field of mechanical connections, steel coarse-threaded round-head screws, with their advantages of easy installation and balanced force distribution, are widely used in core areas such as automotive manufacturing, infrastructure projects, and new energy equipment. Recently, influenced by downstream demand upgrades, policy orientations, and international trade environments, this category has shown a development trend of accelerating technological iterations and optimizing market structures. The industry landscape is gradually reshaping.
In the demand market, new energy and high-end manufacturing have become the core growth engines. Data shows that the market size of China's industrial standard fasteners is expected to reach 220 billion yuan by 2025, with the growth rate of screw products being the fastest, at 9% per year. Steel coarse-threaded round-head screws, as the mainstream category, are particularly prominent in the field of new energy vehicles, suitable for chassis assembly, battery group fixation, etc. As the proportion of dedicated fasteners for new energy vehicles increases to 18%, the usage of high-strength steel coarse-threaded round-head screws continues to rise, and the export of products with tensile strength above 800 MPa has increased by 11%, becoming a key driving force for the growth of this category. At the same time, the expansion of new energy equipment such as wind power and photovoltaics has pushed this type of screws to upgrade towards higher temperatures and anti-loosening capabilities, and the application rate of phosphating and painting composite technology has significantly increased.
In terms of technology, the production process has shifted towards precision and greenness. Leading enterprises generally adopt cold heading technology to upgrade their production lines. Through precise molds, the forming size of the round heads can reach an accuracy of ±0.05mm. The thread processing uses the rolling thread technology, which not only raises the precision to the 6g level, but also enhances the thread strength by 10%-20% through cold hardening. Green manufacturing has become a consensus in the industry. The penetration rate of environmentally friendly processes such as cyanide-free electroplating and passivation treatment is gradually increasing, replacing the traditional galvanizing process. This not only meets the requirements of the EU carbon border adjustment mechanism (CBAM), but also improves the corrosion resistance of the products. The salt spray test life of the colored zinc coating can reach 48-96 hours. In addition, intelligent transformation has been accelerated and implemented. The penetration rate of the MES system is 40%. The application of AGV intelligent warehousing has shortened the delivery cycle from 15 days to 7 days, significantly improving production efficiency.
In terms of international trade, it shows the characteristics of "increased volume and stable price, with differentiated structures". In 2025, the total export value of fasteners from China was approximately 11.919 billion US dollars, increasing by 4.1% year-on-year. Among them, the export performance of the high-strength screw category, which belongs to steel coarse-thread round-head screws, was particularly outstanding. However, the risk of trade frictions still exists. In October 2025, Mexico initiated an anti-dumping investigation on steel bolts from China, and the involved tariff codes covered the relevant coarse-thread screw categories. The investigation period covered the entire year of 2024. Domestic enterprises are actively responding by optimizing overseas layouts and deeply penetrating the ASEAN market to avoid risks. In 2025, the export of similar products to Vietnam increased by 41%.
In terms of the industry competition landscape, both the concentration of the leading enterprises and the breakthrough of the high-end products are underway. The market share of the top 10 enterprises has risen to 35%. The leading enterprises have strengthened their advantages through new material research (with the application of high-strength steel accounting for 50%) and intelligent transformation. However, the problem of excessive low-end production capacity still exists, and 65% of the low-end production capacity is facing a shakeout. At the policy level, the "15th Five-Year Plan for the Development of Mechanical Foundation Components Industry" promotes the independent control of key fields' fasteners, and fiscal subsidies are tilted towards high-end products, providing support for the technological upgrading and import substitution of steel coarse-thread round-head screws.
