Difference Between Reverse Thread And Fine Thread Of The Nut

A. Definition of Nut Counter Thread and Fine Thread

Nut counterthread and fine thread are both a kind of threaded connectors, which are used to fix the coupling and disassembling of mechanical parts and structures, and are usually used in the fields of machinery, chemical industry, electric power and so on. Both types of connectors are threaded, but there are differences.

Nut counterthread means that the direction of rotation of the thread is opposite to the direction of the thread normally used, i.e., the direction of rotation is reversed when tightening and unthreading. In contrast, "fine threads" are threads with a relatively small pitch.

B. Difference between nut reverse tooth and fine tooth

The main difference between nut reverse thread and fine thread is in the direction of rotation and pitch.

1. Rotational direction: the rotational direction of the nut counterthread is opposite, while the fine thread rotates in the same direction, the same direction as the thread normally used. Therefore, you need to pay attention to the selection of rotation direction when using.

2. Pitch: The pitch of fine threads is shorter than that of nut counterthreads, and the pitch is relatively thin. Therefore, in terms of bearing capacity and fastening force, the nut counterthread is more excellent.

C, the scope of application of the nut counterthread and fine teeth

Nut counterthread is commonly used in low-speed, small torque equipment connections, such as instruments, meters, electrical equipment, etc.; while fine thread is used in high-speed, high-torque equipment connections, such as automobiles, airplanes, trains and other mechanical equipment.

Fourth, how to choose the right threaded connectors

Selecting the right threaded connector requires consideration of several factors, such as load capacity, fastening force, use of the environment, the connection method and so on. According to the characteristics of the connected parts and the use of the environment, select the appropriate threaded connectors. When selecting, it is necessary to pay attention to the differences in the direction of rotation and tooth pitch.

In conclusion, the difference between a nut reverse thread and a fine thread lies in the direction of rotation and tooth pitch. Choosing the right threaded connectors requires consideration of several factors, which need to be selected according to the situation in the actual application.
