ZJK Industrial

ZJK Industrial Co., Ltd. is a Chinese manufacturer anchored in Shenzhen's hardware ecosystem, producing custom screws, fasteners, and precision metal parts for consumer electronics. The firm supplies components used in smartphones, wearables, and electric vehicles. Its client list is not publicly disclosed but it operates in the orbit of major Asian assembly partners. Its production focuses on micro-screws and structural fasteners — small, high-tolerance components that hold together devices made by Apple, Huawei, and Xiaomi. ZJK also provides parts for automotive electronics, including connectors and sensor housings used in electric vehicle supply chains serving BYD and Tesla's Shanghai factory. The company competes with firms like Shenzhen Everwin Precision and Jabil's local subsidiaries, often through direct contracting rather than public bidding. The firm maintains a manufacturing campus in Shenzhen with an additional facility in Vietnam, established to diversify supply chains amid trade tensions. Employment is estimated in the mid-hundreds, and the company exports primarily to Southeast Asian assembly plants. It does not publicly report revenue, though shipping records and customs data suggest a nine-figure RMB annual turnover. ZJK Industrial's structural distinction lies in its tier-two position: it does not design products or hold major IP, but it has achieved qualification as a direct supplier for Foxconn and Luxshare assembly lines. This gives it an unusual durability in a sector where most fastener firms remain anonymous and interchangeable. Its Vietnam expansion, completed in 2023, further entrenches a position few competitors have replicated.
