HELICOIL® Smart – The thread insert with tang which does not have to be broken off

The new generation of thread technology for high‑strength joints.

HELICOIL® thread insert

We continue to make product history

The new HELICOIL® Smart is a further 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.
