Tangless inserts are made by processing diamond-shaped materials into coils. When inserted for reinforcement of female threads, it is fixed to the base metal by spring-back action. By inserting and using soft metals, cast iron, resin, and other materials with weak internal threads, a reliable and strong screw fastening force can be obtained.

With Advanex

The use of dedicated tools enables insertion and extraction without tang insertion. There is no damage to female screws or inserts when pulling out. Insertions can be from either front or back without directionality. The insertion tang is not required to be folded, folded, and gauge checked after insertion. This greatly reduces the work time.
