Advantages of installing threaded sleeves

Threaded sheaths are mainly used for the repair and manufacture of screw holes and play a big role. The material is stainless steel, which has high hardness and extremely smooth surface. It can be used in hazardous environments. Threaded sheaths are elastic fasteners. , improving the load-bearing capacity and fatigue resistance of threaded connections.

Wire thread inserts are divided into two types: ordinary type and locking type. The locking type adds one or more locking rings to the ordinary type. The wire thread insert is embedded in the threaded hole of low-strength engineering materials such as aluminum, magnesium alloy, cast iron, fiberglass, plastic, etc., and can form standard M, MJ threads. It has the functions of high connection strength, earthquake resistance, impact resistance and wear resistance. It can also disperse stress and protect the threads of the base body, greatly extending the service life of the base body. In addition, the wire thread insert can also be used as a repair method when the thread on the original base body is tripped or out of thread, without causing the entire base body to be scrapped. The maintenance is convenient, fast and economical.

Special tools for wire thread inserts are required to install wire thread inserts, including special taps for wire thread inserts (ST taps), wire thread insert installation wrenches, punchers, sleeve removers and wire thread insert bottom hole plug gauges. Among them, the tap is used to process the internal thread for installing the wire thread insert; the installation wrench is used to screw the wire thread insert into the threaded bottom hole of the base body; the puncher is used to punch out the installation handle of the wire thread insert with a break groove; and the unscrewing device is used to remove it A wire thread insert inserted into the threaded bottom hole of the base body; the bottom hole gauge is used to detect the threaded bottom hole.
