DIN8140 Wire thread insert

Steel wire screw sleeve 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 a standard internal thread, and then screwed into the bolt (or screw), also known as thread sleeve, referred to as thread sleeve. It is a spring-shaped concentric body with internal and external threads 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. Its principle is to form an elastic connection between the screw and the thread in the base body, eliminate the thread manufacturing error and improve the connection strength. The steel wire screw sleeve is embedded in the threaded holes of low-strength engineering materials such as aluminum, magnesium alloy, cast iron, glass fiber reinforced plastic and plastic, which can form high-precision internal threads conforming to international standards. It has the functions of high connection strength, earthquake resistance, impact resistance and wear resistance, and can disperse stress to protect matrix threads, greatly prolong the service life of matrix, and is widely used in electronic applications.
