The thread sheath is made of high-quality stainless steel wire, with rhombus cross-section and spring-shaped thread by mechanical rolling. The diameter  of the sheath is larger than that of the screw hole. When the sheath is installed,  it is compressed and tightened. After the installation, it will spring back to its original state, so that the sheath is permanently fixed in the screw hole. Because of its large diameter,

the thread sheath has a larger contact surface, so it is stronger than the original thread.
