Are helicoils strong?
If a thread is “static” i.e. not likely to be done up and undone more than a few times in its lifetime, we would always say a helicoil type thread is the strongest option. There is not a lot of difference in strength between a Time-Sert and a wire STI and both protect soft alloys from stripping.
How do you remove a stripped HeliCoil?
Occasionally HeliCoil inserts must be removed. Inserts may be removed manually with a little effort. This is done by inserting the blade of the extracting tool into the HeliCoil insert so that the V section of the blade is toward the top end of the insert.
