Brass hollow hexagonal screws
The double-through round knurled copper post is a common precision connecting element. It is cylindrical in shape, with internal threads at both ends and an anti-slip knurled texture on the outer surface. This product conforms to relevant precision machinery industry standards and is indispensable in applications requiring intermediate connections, support, and positioning in electronic equipment, instruments, PCB board mounting, and optical equipment, demanding good conductivity and convenient manual operation. It provides reliable spacer support and bidirectional threaded connections. To enhance the product's conductivity and anti-slip performance, we use high-quality brass or copper and precision CNC turning, or perform deep strengthening and anti-oxidation polishing on the knurled surface. This significantly improves the product's grip comfort and long-term durability.
