Quanzhou, China (2000)
From its 2000 inception as Quanzhou Xiandai Auto Parts, Quanzhou Zhongke Auto Parts Co., Ltd. has pioneered China’s critical fastener manufacturing. Founded by visionary industrialist Mr. Jiang, the company began with specialized U-bolt production for commercial trucks——laying the foundation for what would become a globally integrated enterprise.
Strategic Product Expansion (2000-2022)
While maintaining U-bolt market leadership, Zhongke systematically broadened its portfolio:
2005: Launched center bolts for axle retention systems
2010: Engineered hub bolts meeting ISO 4108 standards
2018: Developed track shoe bolts for Caterpillar-equivalent machinery
2020: Added DIN-certified components (DIN 960, 961, 6921, 912, 6923) for European OEMs
Globalization Milestone (2022)
Establishing the ZK International Brand marked Zhongke’s strategic shift:
• DIN products TÜV-certified within 6 months of launch
