Brass hollow hexagonal screws
The brass external hexagonal hollow screw is a special fastening connector with a standard hexagonal head and a through-hole internally machined to form a hollow structure. The external hexagonal head facilitates operation with a wrench. This product conforms to relevant national standards (GB/T 6170) and German standards (DIN 934), and is indispensable in hydraulic systems, pneumatic devices, precision instruments, and other applications requiring liquid or gas passages and demanding good conductivity and corrosion resistance. It serves the dual purpose of fastening connections and facilitating media flow. To enhance the screw's corrosion resistance and electrical conductivity, we use high-quality brass and precision-machine it, or perform precision roll forming and surface polishing on the threaded parts. This significantly improves the thread accuracy and service life of the product.
