This thread insert merges the advantages of the HELICOIL® Plus and the HELICOIL® Tangfree. There is a tang, but it does not have to be broken off and removed. The installation time is therefore reduced by approx. 20 %. Every thread of the thread insert with precision-formed, rhombic profile is free running. The result is a true-to-gauge internal thread including the last thread which is in every case threadable.
Just like the HELICOIL® Plus, the HELICOIL® Smart is provided with a special thread start to allow easier installation in a holding thread.
