High corrosion-resistant wire threaded insert with cadmium plating

The wire thread insert is made of high-quality austenitic stainless steel material. It forms a reliable internal thread after installation and embedding. It can significantly improve the strength and safety of low-strength engineering materials such as aluminum, magnesium, copper alloy, plastic, plexiglass, and bakelite. Wear resistance; applied to steel parts, cast steel, and cast iron, it can improve the durability of screws, prevent screws from loosening and falling off, fatigue fracture due to various vibrations, and improve the fatigue resistance of screws during connection. The advantages of wire thread inserts are: high wear resistance and tensile strength, low thread friction, high surface quality, and excellent anti-corrosion and heat resistance.

Wire thread insert, also known as thread sheath, thread insert, is an insert developed to protect non-ferrous metal thread holes, is a new type of internal thread fastener, suitable for threaded connection, screw and fasten in the threaded hole of one of the connected parts, forming a standard internal thread, and then screw the bolt (or screw) into it. It is a spring-like internal and external thread concentric body made of cold-rolled diamond stainless steel wire. It is mainly used to strengthen and protect the internal thread of low-strength materials, eliminate thread manufacturing errors, improve connection strength, effectively reduce the effect of uneven thread acceptance and anti-shock vibration, and extend the life of thread holes.

Cadmium-plated steel wire thread insert has the basic properties of steel wire thread insert, but also has the corrosion resistance, lubrication and stability of cadmium-plated material.

1. Enhance the connection strength, improve the connection conditions. Low strength materials such as aluminum and magnesium are used to avoid wire slip and misalignment, and excellent connection performance is obtained.

2. Wear resistance. It is used for the parts that are often disassembled, which can greatly improve the service life of the thread. Reduce the damage to the matrix with low strength, reduce the processing cost of the matrix and the invisible cost such as replacement and failure

3.Its excellent corrosion resistance, so that the screw can be matched with most materials in the conventional environment. The threaded connection can also be prevented from sticking or chafing at high temperatures.

4.Increase the force surface. It is used for parts requiring a strong connection without increasing the diameter of the thread hole.

5. Anti-vibration and anti-loose. Especially for spacecraft and other products require high safety factor occasions.

6.Easy maintenance. The damaged thread holes loaded into the wire thread insert, which can continue to be used after repair to avoid the possibility of reporting damage to the workpiece.
