30 Years of Manufacturing Excellence & Global Trust
Since 1996, XIJI Fastener has bridged the gap between complex engineering needs and reliable supply chain solutions. From our 4,500 m² production base in Zhejiang, we deliver precision fasteners (M3-M90) to industrial leaders in 30+ countries.
30 Years of Forging Industrial Trust
From Local Craftsmanship to Global Supply Excellence
Founded in 1996, XIJI Fastener began its journey as a specialized workshop in the heart of China’s fastener manufacturing hub. Over three decades of steady growth, we have evolved into a 4,500 m² integrated manufacturing and trading powerhouse.
We solve the most common challenges for international buyers—inconsistent quality and fragmented communication—by offering a seamless ‘Factory + Trade’ model. This allows us to combine the direct cost-efficiency of our own production lines with the high-level technical expertise required by global industrial standards.
