Introduction to Bolt Insert
The use of the pin sleeve mainly includes the following points:
1. Enhancement of thread strength: the pin sleeve is mainly used to enhance and repair the strength of the internal thread, especially in low strength materials such as aluminium alloy, magnesium alloy, cast iron, plastics, etc., through the installation of the pin sleeve can significantly increase the bearing capacity of the threaded holes and fatigue resistance.
2. Thread Repair: when the original internal threads due to wear and tear, damage, or slippage of the teeth, such as the loss of function, through the installation of the pin sleeve can quickly and effectively restore the standard size and performance of the threaded holes to prolong the service life of the threaded holes.
3. The installation of the pin sleeve can quickly and effectively restore the standard size and performance of the threaded hole and prolong the service life of the threaded hole. 3. Anti-loosening: Due to its special locking design (pin key on the external thread), the pin sleeve is not easy to loosen after installation of bolts or screws, thus enhancing the stability of the threaded connection, which is especially suitable for vibration and impact environments.
4. Increase the size of threaded holes: In case of insufficiently large threaded holes or the need to replace them with larger size holes, it is possible to increase the size of threaded holes. hole is not large enough or need to replace the larger size of the bolt, the installation of the pin sleeve can expand the internal threaded hole diameter, to provide the required larger size of the threaded connection.
5. corrosion: the pin sleeve is generally made of stainless steel and other corrosion-resistant materials, after the installation of the resistance to chemical corrosion and oxidation, to extend the service life of the threaded holes in harsh environments.
6. standardisation of threads: the installation of the pin sleeve can be converted into a standard threaded hole in the non-standard or irregular threaded holes. Installation of the pin sleeve can be converted into high-precision internal threads in line with international standards. In short, the pin sleeve is widely used in aerospace, automotive manufacturing, rail transport, machinery and equipment, precision instruments and other fields, effectively improving the reliability, durability and safety of threaded connections.
