Can you put 2 helicoils in the same hole?
Re: Stacking Helicoils That way the last one you installed should be setting ok and not trying to climb up on the first one. You’re first using the STI tap, so both helicoils will be ligned up thread wise. You’ll have to lock-tite them in so they stay put. Then just remove the tangs.

However, there are some uses for thin walled thread inserts where we would not recommend helicoil type inserts but Time-Serts.
How does a helicoil work?
