M8 M10 M12 M16 Thread Insert Fastener Stainless Steel 304 Used In Sheet Metal
Information
Wire thread insert is a new type of internal threaded fastener, suitable for threaded connection. It is screwed into and fastened in the threaded hole of one of the connected parts to form a standard internal thread. The bolt (or screw) is then screwed into it. Also known as threaded wire sleeve, wire sleeve for short. It is a spring-like internal and external thread concentric body precisely processed with high-strength, high-precision, and smooth-surface cold-rolled diamond-shaped stainless steel wire. It is mainly used to enhance and protect internal threads of low-strength materials. The principle is to form an elastic connection between the screw and the thread inside the base, eliminate thread manufacturing errors and improve the connection strength.
Performance
Wire thread insert is a new type of connection and fastening technology, which can effectively improve the connection conditions during screw connection and greatly improve the reliability of screw connection. Its advantages are as follows:
1. Wire thread inserts are used in various low-strength materials, which can greatly improve the wear resistance of screw connections and avoid damage to the connecting threads.
2. Due to the certain elasticity of the wire thread insert, the load distribution on each circle of the thread can be more uniform, eliminate the pitch and thread deviation between the screw and the screw hole, and can absorb vibration, thus improving the connection strength and resistance of the thread. Fatigue strength.
3. Compared with the method of inserting steel or copper bushings, under the same strength conditions, screws with smaller size and higher strength can be selected, which can reduce the volume and reduce the weight.
4. The hardness of the wire thread insert is higher than that of the screw, so it is less worn during the assembly and disassembly process of the screw connection and can be used repeatedly. According to related experimental studies, the tensile strength of the wire thread insert is more than 7 times that of the screw, so the wire thread insert will not be damaged even if the screw is broken.
Use
1. Enhancing the connection strength and improving the connection conditions. Low-strength materials such as aluminum and magnesium are selected for the wire thread insert, which can avoid slippage and wrong teeth, and obtain excellent connection performance.
2. Wear resistance. Used in frequently disassembled parts, it can greatly improve the service life of the thread.
3. Increase the bearing surface. It is used in places where strong connection force is required and the diameter of the screw hole cannot be increased.
4. Anti-loosening. It is especially used in occasions where products such as spacecraft require a high insurance factor.
5. Easy to maintain. Install the damaged screw hole into the wire screw sleeve, and continue to use it after repairing to avoid the possibility of damage to the workpiece.

Install
Special tools for wire thread inserts are required to install wire thread inserts, which mainly include special taps for wire thread inserts, wire thread insert installation wrenches, punches, unscrews, and bottom hole plug gauges for the internal thread of steel thread inserts. The taps are used for processing. The installation threaded bottom hole of the wire thread insert, the installation wrench is used for the installation of the wire thread insert, the punch is used for the punching of the mounting shaft, the unloader is used for the disassembly of the threaded sleeve, and the bottom hole plug gauge is used for the inspection of the bottom hole of the installation.
