What Is a Thread Insert?
Coil thread inserts (wire thread inserts) include the name (steel wire sleeve, screw sleeve, wire sleeve, threaded wire sleeve, thread sheath, etc.).
Coil thread insert
- Special tools for wire sleeves are required for the installation of wire sleeves, which mainly include wire taps, wire sleeve installation wrenches, breakers, unloaders, and wire hole bottom hole plug gauges, of which taps are used for processing Threaded bottom hole for installation of steel screw sleeve, installation wrench is used for installation of steel screw sleeve, punch is used to install the breaking of the tail handle, sleeve remover is used for removal of the screw sleeve, and the bottom hole plug gauge is used for the inspection of the installation bottom hole .
- 1. Bottom hole tap: It is used for the processing of the internal thread installation of the wire screw sleeve. Since the external thread of the wire screw sleeve is a non-standard thread, this tap is different from the ordinary M tap in size.
- 2. Installation wrench: It is used for the installation of the wire nut in the bottom hole of the thread. The basic principle is to pass the wire nut through a section of the guide thread to force the outer diameter of the wire nut to shrink so that it can be smoothly inserted into the bottom hole. And automatic two.
3. Breaker: The purpose of the breaker is mainly to break the installation handle of the wire screw sleeve, especially for the through hole, the installation handle must be broken.
4. Sleeve remover: It is used to take out the steel wire sleeve installed in the threaded hole of the base body. For long-term use, the screw sleeve needs to be replaced, and when it needs to be removed due to improper installation or thread jumper during installation use.
5. Thread plug gauge: used for the detection of the inner thread bottom hole of the wire nut installation. After the wire nut installation, the accuracy of the internal thread formed depends on the profile manufacturing tolerances of the wire nut and the inner thread bottom hole of the wire nut. tolerance.
- The coil thread insert is installed using a special tap and installation tool for tapping and installation. The coil thread insert is installed in the screw hole or nut, which can reduce the uneven force of the thread teeth and resist shock vibration, and can improve the fatigue strength of the thread. , Reduce thread wear and corrosion resistance, and extend screw hole life.
- Standard products can be used for stably assembled components. Therefore, the inserts are made of various materials and have the same bonding strength, allowing high shrinkage loads in their applications.
- 1. Enhance connection strength and improve connection conditions. The steel wire sleeve is selected from low-strength materials such as aluminum and magnesium, which can avoid slipping and misalignment, and obtain excellent connection performance.
- 2. Abrasion resistance. Used for frequently disassembled parts, which can greatly increase the service life of the thread.
3. Increase the force surface. It is used for the parts that require a strong connection force but cannot increase the diameter of the screw hole.
4. Prevent loosening. It is especially used in occasions where products such as spacecraft require a high insurance factor.
5. Easy maintenance. Put the damaged screw hole into the wire screw sleeve, and you can continue to use it after repair to avoid the possibility of workpiece damage. [2]
- The coil thread insert has been tested on the product for a long time, and has a reliable structure, good performance and convenient use. It can be used on product parts in various industries, and there are products using screws, all of which are objects, such as:
- aviation industry
- Shipbuilding industry
- Defense industry
- auto industry
- Hardware electronics
- Various machinery
