Product Description
ZhongYang company (ZY SCREW) was founded in 2006. Located on Zhoushan Islands, it is a manufacturing enterprise specializing
in the design and produce precise screws and barrels. It is one of the top 10 local screw production companies .In March 2023, the company moved. Now it has one of the largest workshops in the screw industry.
In the next six months ,a new nitriding workshop and bimetallic workshop will be built .
