[0002] Wire thread insert is a new type of internal thread fastener. It is a spring-shaped internal and external thread concentric body made of high-strength, high-precision, smooth-surface cold-rolled diamond stainless steel wire. It is mainly used to enhance and protect the internal thread of low-strength material. Due to its own characteristics, an installation handle bent toward the center, that is, the tail handle, is formed at the end of the wire thread insert.
