Coal mine nuts are mainly used in the coal mine industry to strengthen and firmly connect the parts in various equipment, prevent loosening and falling off accidents in the process of coal mining and transportation, and ensure coal mine safety ‌.

 Advantages of Tianlong Mine Torque Nuts

 1. Tianlong mine torque nuts are made of high - quality Q235 and 45 steel

Tianlong mine torque nuts are crafted from high - quality Q235 and 45 steel, which are among the most widely applicable materials. Both of these steels are commonly used and feature stable quality.

- Q235 has good plasticity, toughness, and weldability, making it suitable for scenarios where relatively low strength is required, such as the connection of simple support equipment in coal mine roadways.

- 45 steel has high strength and hardness. After Tianlong's heat treatment, its comprehensive mechanical properties are even better, making it suitable for the key fastening parts of heavy - duty mining machinery and equipment.

 2. Mine torque nuts with a wide range of applicable specifications

The thread sizes of Tianlong mine torque nuts range from M16 to M24, which is a very common specification range for mining equipment. This means that whether it is for the connection of anchor rods used in roadway support or the fastening of components of mining machinery and transportation equipment, you can find suitable ones at Tianlong.

 3. Tianlong mine torque nuts with multiple surface treatment processes

- Plain: Without an additional coating, it has a relatively low cost and is suitable for relatively dry areas within mines that are free from chemical corrosive media.

- Black: The surface of the nut has a dense oxide film, which improves the nut's rust - prevention ability and is suitable for areas in mine shafts with long - term water dripping.

 4. Rich performance grades

Tianlong mine torque nuts offer several performance grades to choose from.

- Grade 4.8 is relatively cost - effective.

- Grade 8.8 nuts have moderate strength and hardness.

- Grade 10.9 mine torque nuts have high hardness and large tensile strength, making them suitable for the connection of the drum of large hoists, the fastening of components of heavy - duty excavators in open - pit mines, etc.
