Can helicoils be torqued?

from Cleveland, Ohio. C9 said: Helicoils are stronger than the original threads, especially so in aluminum. Torque is all about the bolt and stretching it to – but not beyond – what’s called it’s modulus of elasticity.

Which is stronger a helicoil or a TIME SERT?

There is a structural difference in the time-sert vs. the helicoil in that the time-sert is a solid piece, thus distributing the thread load across the full depth of the bore. This is important if you consider that the majority of a bolt’s load is carried by the first few threads. So in theory, the time-sert will be stronger.

What are the advantages of TIME SERT inserts?
