Zinc hex coupling nut got widely application in various mechanical and electronic equipment due to their unique structure, diverse material options, and convenient installation characteristics.

1, Structure: Hexagonal female to female thread spacer have internal threads at both ends and a hexagonal column in the middle, which facilitates tool gripping and connection to other components.

2, Material: Carbon Steel

3, Surface Treatment: Zinc plating

4, Size Description: Main dimensions include thread size and hexagonal length.

For example, M3x10 indicates an M3 internal thread and a hexagonal length of 10mm.

Metric Sizes: M2.5 M3 M4 M5 M6 M8

Imperial Sizes: #4-40 #6-32 #8-32 #10-32

Length: 3mm-80mm

(If the above specifications do not meet your requirements, we can provide customized services)

5, Installation and Use: The hexagonal design makes the installation process more convenient, allowing for fixing without additional tools, thus can improve installation efficiency.

6, Application Scenarios: Hex coupling nut are widely used in mechanical structures requiring double-sided connections, such as machine tool bases, vehicle hubs, mechanical housings, and circuit board spacers.

Zinc hex coupling nut of different specifications and materials are suitable for different application scenarios. For example, high-strength materials are suitable for heavy-duty structures, while fine-pitch threads are suitable for high-precision or anti-loosening applications. Customers can choose the most suitable material and specifications according to their actual needs.
