A quantum leap in the HELICOIL® thread technology

The new HELICOIL® Smart is a quantum leap in the HELICOIL® thread technology. A coil thread insert with tang which does not have to be broken off.

The innovation

The installation mandrel bends it backward during spinning off and then compresses it. This smart thread insert merges the advantages of the HELICOIL® Plus and the HELICOIL® Tangfree.

Precision at its best

The HELICOIL® Smart thread insert, which is made from a wire with rhombic profile, is also formed into an elastic spiral. As to the Free Running version, thread by thread it is a completely free running coarse thread. The result is a true to gauge internal thread including the last thread which is in every case threadable. It produces high strength threads transferring forces from flank to flank into the holding thread.

2 in 1 installation mandrel

To screw in the thread insert, all you need is the Smart installation mandrel of similar size as a tap. Very special is the blade position control. Upon screwing in, the blade has a pull in function, whereas upon screwing out, it turns into a bending and compression tool.
