Future of CNXD

We Carry Two DNA Strands

The first comes from CNRL, where my father spent 30 years shaping OEM fastener standards and building a reputation for millimeter-level precision. This is the root of our “pre-market” expertise.

The second comes from JINKE, a shareholder of Xuanda, known for its deep experience in the aftermarket. This is the force that drives us to bring OEM-level quality into service networks, distributors, and repair shops worldwide.

As the second-generation founder, with 7 years of study in Australia and 10 years of international trade experience, my role is to weave these two legacies into one brand—OEM heritage plus aftermarket agility. CNXD stands for a complete fastener solution, ensuring every connection, whether at production or repair, carries the same reliability.
