DIN8140 Wire thread insert is a new type of internal thread fastener, which is suitable for thread connection. It is screwed into and fastened in the threaded hole of one of the connected pieces to form standard internal thread, and bolts (or screws) are screwed into it. It is also called thread screw sleeve, which is referred to as thread sleeve for short. It is a spring-shaped internal and external thread concentric body made of cold rolled diamond stainless steel wire with high strength, high precision and smooth surface, which is mainly used to enhance and protect internal threads made of low strength materials. The principle is to form an elastic connection between the screw and the thread in the base body to eliminate the thread manufacturing error and improve the connection strength. The steel wire screw sleeve is embedded into the threaded holes of low-strength engineering materials such as aluminum, magnesium alloy, cast iron, glass fiber reinforced plastic, plastic, etc. It can form high-precision internal threads conforming to international standards, has the functions of high connection strength, earthquake resistance, impact resistance and wear resistance, can disperse stress to protect the threads of the matrix, greatly prolong the service life of the matrix, and is widely used in electronic applications.
