China is the world’s largest producer of fasteners, accounting for more than 40% of global annual output of screws, nuts, and bolts. The sector boasts a vast number of market players, yet it has long grappled with a structural imbalance: “low-end oversupply and high-end shortages.” Over 80% of domestic production capacity is concentrated in ordinary standard fasteners below Grade 8.8, leading to fiercely competitive pricing and steadily shrinking profit margins. Meanwhile, high‑strength Grade 12.9 bolts, specialty alloy nuts, and miniature precision screws—essential for aerospace, semiconductor equipment, offshore wind power, and advanced medical devices—remain less than 30% domestically produced, with many critical components still reliant on overseas imports.

For a long time, the fastener industry has relied on manual sampling inspections to verify appearance and dimensions. With an extensive variety of screws, nuts, and bolts—each available in numerous specifications and often of very small sizes—human inspection is prone to fatigue‑induced omissions. Hidden defects such as thread damage, head cracks, dimensional deviations, and poor plating are difficult to detect adequately. Once defective products reach downstream customers, they can easily lead to safety hazards, including equipment loosening and structural failures.

In recent years, the production and sales of new-energy vehicles in China have continued to expand, with vehicle architectures evolving from 400V platforms to 800V high-voltage systems. This shift has prompted new technical standards for fasteners—such as nuts, bolts, and screws—in power batteries, integrated die-cast body structures, and electric drive systems, driving a structural transformation across the fastener industry.
