JX-21JG154-M3-56-H4.72-B, Brass Male-Female Threaded Hex Standoffs M3

 They have good corrosion resistance and are passivated for enhanced protection. They may be mildly magnetic. The flat sides of the hex ensure a firm grip when tightening with a wrench.The hexagonal Isolation Column, as the name suggests, has one end male (external thread) and one end female (internal thread). Apart from copper, it can also be made from stainless steel or carbon steel, although copper is the most commonly used material. Therefore, it is sometimes also referred to as a copper isolation column.

There are two types of copper isolation columns. One type is shown in the upper right picture, which consists of one external thread and one internal thread, and this design is called a male-female screw. The other type is a hexagonal rod with internal threads throughout, and it is called a copper isolation column or spacer. The spacer is mainly used in chassis cabinets, and circuit boards, providing isolation and support. Depending on the usage environment, different materials and surface treatment methods can be selected. Generally, stainless steel spacers do not require surface treatment, while male-female copper isolation columns can be nickel-plated or galvanized. Juxin Company uses high-precision CNC automatic lathes for production, adopting a real-time monitoring system with one operator assigned to each machine. Real-time inspections are conducted every five minutes on the production line to monitor product quality. After production, the products are sampled and inspected by technicians in the inspection area. Only after passing the inspection conducted by the warehouse can they be packaged and shipped, ensuring a 100% qualification rate for hexagonal isolation columns reaching customers' hands.

1. These support columns are widely used in various applications such as circuit boards, electrical appliances, computer cabinets, connectors, etc. They provide support, isolation, and fastening functions during use. We can customize various specifications according to the customer's actual needs. The support columns produced by Juxin are made of authentic 3604 brass. The company can also produce SUS303 stainless steel support columns and 1214 quick-cut steel hexagonal support columns. The raw materials and surface treatments comply with ROHS standards. Support columns are generally available in circular and hexagonal shapes, and can be made according to the user's specific requirements.

2. Surface treatment: Common surface treatments for copper columns include galvanization, nickel plating, tin plating, gold plating, silver plating, etc. The choice can be made based on specific requirements.

3. Material specifications: The specifications of support columns mainly include M3, M4, M5, M6, M8, M10, etc., with corresponding hexagonal sizes of 5mm, 6mm, 8mm, 10mm, 12mm, 15mm, among which the M3 series is the most commonly used. In addition to copper, materials such as stainless steel and quick-cut steel are also available.

4. Production and processing: The production mode of male-female screws involves directly using hexagonal rods. The material enters the machine through the feeding port and undergoes processes such as turning and tapping to form the final product in one step.

Packing: Inner is Poly foam, out is carton. Then pallet. Carton size: 29*19*19.5CM and 23.5*17.5*8, CM and pallet size is: 215*100*90CM, or as your requirement.
