Characteristics of steel wire screw sleeve

 the diameter of the steel wire thread sleeve in the free state is slightly larger than the diameter of the screw hole it is installed in. During the assembly, the steel wire thread sleeve is subject to the torque of the special wrench to make its diameter smaller. It enters into the screw hole that has been tapped with the special tap. After the installation, the steel wire thread sleeve has the similar function of spring expansion, so that it is firmly fixed in the screw hole, and will never be brought out with the screw out.

Fine thread: pitch must be marked to show the difference between coarse thread and fine thread. The feature is just opposite to coarse thread. It is specified to supplement the special use requirements that coarse thread can not meet. Fine thread also has pitch series, which is mainly used in metric pipe fittings of hydraulic system, mechanical transmission parts, thin-walled parts with insufficient strength, internal parts with limited space and shafts with high self-locking requirements And so on.
