1. Name of producer: mine shake shaped nut

 

2 Material specifications:
generally ordinary carbon steel, alloy steel, etc., high strength steel can be selected according to the use requirements. Its master

The specifications are shown in the following table:

 

3. Material specification:

Ordinary carbon steel Q235, Q345, 45#, 10#, etc

Alloy steel 35CrMo, 40Cr, 42CrMo, etc

High strength steel 20MnTiB, 30CrNiMo8, 40CrNiMoA, etc

 

4. Thread specification:
The general specification of the thread of the special-shaped nut for mining is M16~M64, and there are three main forms of thread: ordinary thread, left thread, trapezoidal thread. Among them, the difference between the left thread and the ordinary thread is that the rotation direction is opposite, which is usually used for special applications.

 

5. Special-shaped structure:
The special-shaped structure of mine nuts is mainly divided into three kinds: hexagonal special-shaped, flat hexagonal special-shaped and square special-shaped. Among them, the hexagonal shape is the most commonly used one for connecting fasteners, the flat hexagonal shape is mainly used for connecting pipes and valves, and the square shape is used for connecting the plate structure to achieve a stable and firm connection effect.

6. Surface treatment:
The surface treatment of special-shaped nuts for mining is generally galvanized, hardened, sprayed, etc., according to the requirements of use

Choose different surface treatments.

 

7. Other requirements:
Other requirements of mine shaped nuts such as tensile strength, torque resistance, corrosion resistance according to different requirements

Vary with requirements.

 

In short, the selection of specifications and models of special-shaped nuts for mining should be based on the specific use requirements and environmental characteristics, and the appropriate materials, thread specifications, special-shaped structure, surface treatment, etc., should be selected to ensure that fasteners can meet the requirements of high-strength connection, stability and corrosion resistance during use.
