Thread Insert

The wire thread insert is made of high-hardness and corrosion-resistant steel wire with a diamond-shaped cross section. It is a spring-like internal and external thread concentric body. The outer thread is screwed into the thread groove of the wire screw sleeve, and the inner thread is connected. The standard internal thread used for fastening the piece has a cross-sectional shape of a combination of two internal and external threads. The wire thread inserts are divided into two types: free running insert and screw lock insert.
