Practical applications of stainless steel long nut threaded sleeves include:

Improving joint strength: For aluminium, magnesium and other low-strength alloys, it can effectively improve the joint strength of the thread.
Improve wear resistance: For bolted connections, it can prevent damage to the connecting threads and improve wear resistance.
Improve load distribution: Due to its elasticity, it can make the load distribution on each ring of the thread uniform, eliminate the deviation of pitch and tooth shape, thus improving the load-bearing capacity and fatigue strength of the threaded connection.
Prevent loosening: The threaded sleeve with lock can lock the screw under strong vibration to prevent loosening, and is suitable for situations with high insurance factor.
Convenient maintenance: For damaged internal threads, the installation of threaded sleeves can be repaired quickly and inexpensively, and the original screw can be reused.
Conversion of thread specifications: Easy conversion between metric, imperial or international standard threaded holes.
Due to these advantages, threaded sockets with long nuts made of stainless steel are used in many areas, e.g. in automotive engineering, aerospace, mechanical and plant engineering and the chemical industry.
