Self-locking thread insert HELICOIL® plus

The thread insert with its precision-formed rhombic profile runs through freely turn for turn. The result is an internal thread that is true to gauge and accepts the insertion of a screw at both ends. The dimensional stability of the ISO thread complies with DIN 13 6H, with 4H for special requirements, and meets the requirements of international standard specifications. The green colour of the HELICOIL® Plus Free Running simplifies identification even when installed. The advantages of the HELICOIL® Plus System are particularly apparent with respect to processing and tools, resulting in shorter cycle times.
