Is helicoil stronger than original threads?

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 to use helicoil kit?

Clear the damaged thread using the drill bit provided in the kit.

Using the tap provided,cut the new threads into the hole,using a small amount of cutting oil or cutting fluid for lubrication.

Place the insert on the installation tool and position it so that the tang fits into the slot at the end.

Begin winding the new insert into the hole,twisting until it is secure. Stop when it is about half a turn below the surface.

Unscrew the tool and the insert will remain securely in place.
