The HELI-COIL Thread Repair System
Heli-Coil has the most effective and universally accepted method of thread repair. Heli-Coil inserts quickly and permanently restore stripped, worn or damaged threads to their original size and condition.
Heli-Coil inserts work in any part or material (R)C aluminum, magnesium cast iron, bronze, etc. Increasing use of light weight (and soft) materials means more damage to threads. There is a Heli-Coil repair for virtually every application.
Damaged threads can be restored to better than new condition. The Heli-Coil system makes all other thread repair methods such as welding, plug- ging, over-sized fasteners and over-sized drilling of mating parts, obsolete.It's faster you save time, increase your repair capabilities and restore parts that otherwise would have to be scrapped.
