Wire thread inserts are a novel connection and fastening technology with the following advantages:

1. Wire thread sleeves are used in various materials with low strength, which greatly improves the wear resistance of screw connections and prevents damage to the connection threads.

2. Due to the certain elasticity of the steel wire threaded sleeve, the load distribution on each circle of the thread can be distributed more evenly, the pitch and tooth shape deviation between the screw and screw hole can be eliminated, and the vibration can be absorbed, thus improving the connection strength of the thread.

3. The locking type wire screw sleeve can lock the screw in the threaded hole, so the screw will not loosen when exposed to shock and vibration, which is better than the conventional locking device.

4. Compared with the method of inserting steel or copper bushings, screws of smaller size and higher strength can be selected under the same strength conditions, which can reduce volume and weight.

5. The hardness of the threaded sleeve made of steel wire is higher than that of the screw, so the wear during the assembly and disassembly process of the connection with the screw is low and can be used repeatedly. After relevant experimental investigations, the tensile strength of the threaded sleeve made of steel wire is more than 7 times that of the screw, so that the threaded sleeve made of wire is not damaged when the screw is broken.

The purpose of wire thread inserts:

1. Increase connection strength and improve connection conditions. Wire thread inserts are selected from low strength materials such as aluminum and magnesium, which can avoid slip and misalignment and achieve excellent connection performance.

2. Wear resistance. Used for frequently disassembled parts, which can greatly improve the life of the thread.

3. Increase the contact area. It is used for parts that require a strong connection force and cannot increase the diameter of the screw hole.

4. Loosening protection. It is particularly used when a high insurance factor is required for products such as space vehicles.

5. Easy care. Insert the damaged screw hole into the wire screw sleeve and it can be used further after repair to avoid the possibility of damaging the workpiece.
