China All‑metal self‑locking nut Factory

China's total fastener exports reached 4.673 million metric tons, up 10.9% year-on-year, with export value totaling US$8.96 billion, a 7.7% increase. Monthly performance remained robust, with September exports reaching 516,600 metric tons (up 8.2% YoY) and export value hitting $985 million (up 9.4% YoY).

Lock nuts, also known as anti-loosening nuts or retaining nuts, are commonly used in mechanical equipment. Because they offer excellent locking and anti-loosening performance, many people choose to use them. The following are some common types of lock nuts.

Recently, market research firm Mordor Intelligence released an in-depth report on the global industrial fastener industry through 2026, providing a comprehensive analysis of the industry’s overall scale, growth drivers, technological trends, and regional landscape over the next five years. Data indicates that the global fastener market will maintain steady growth, with high-end sectors such as new energy, aerospace, and wind power serving as the primary growth engines, while material innovation and smart upgrades emerge as the industry’s mainstream development directions.

With Dragon Boat Festival approaching, Jiaxing Aoke will be closed for the holiday from June 19 to June 21.

The trends toward larger turbines and deeper offshore locations place more stringent demands on core components. As core connecting components of wind turbines, fasteners are widely used in critical locations such as tower flanges, blade roots, nacelle bases, and offshore pile foundations. Data shows that over 60% of an offshore wind turbine’s structure relies on fastener connections, while 15%–20% of structural failures in offshore wind turbines are caused by bolt corrosion, loosening, or fatigue failure. It can be said that the quality of fasteners directly determines the operational safety and O&M costs of wind turbines. Extreme operating conditions at sea—including high salt fog, severe typhoons, and continuous vibration—make standard fasteners highly susceptible to rust, loosening, reduced service life, and downtime for repairs. This represents a core pain point prevalent across the industry.

M20 316L Flex Lock Nut is a heavy‑duty all‑metal self‑locking nut. Adopting 316L low‑carbon grade, it restrains chromium carbide precipitation and prevents post‑weld intergranular corrosion, a typical defect of standard 316 fasteners. Its large‑size structure bears high axial preload and shear force, while the radial slotted full‑metal locking design avoids nylon ageing and swelling, sustaining stable anti‑loosening under vibration and shock. Ideal for offshore, chemical, port, new‑energy and rail‑transit equipment. Both standard and custom dimensions, threads and surface finishes are offered for high‑reliability fastening under harsh working conditions.
