The pin-type thread insert is a special fastener with threads both inside and outside, and four or two pin keys on the external thread. The pin-type thread insert is inserted into the bottom hole after tapping, and then the four pins are pressed in to achieve a strong fastening effect.
The product is mainly used in aerospace, railway locomotives, vibrating machinery and other products with high requirements for thread strength. The most basic function of the pin-type thread insert is to repair and enhance the internal thread. As a means of thread repair, the pin-type thread insert can quickly and effectively repair the damaged thread. When applied to materials with low strength, the pin-type thread insert can greatly enhance the strength of the threaded hole.
