Heli-Coil Is either side ok?
Heli-Coil Is either side ok?
(OP)
I know Heli-Coil inserts are usually installed flush with the mating surface. For strength considerations, I want to keep as much unthreaded bolt shank as I can through the joint. Is it acceptable to install the Heli-Coil on the far side of the joint, basically like a nut? I do not see anything in the Heli-Coil literature and specs that forbids this practice.
Thanks!

Could the lower part be tapped only only the bottom, rather than deliberately require a helicoil be fitted and threaded all the way deep into a part? If (during fabrication) any one of many helicoils being threaded into these deep hole gets jammed or breaks off or gets cross threaded, you've lost the whole part. .
RE: Heli-Coil Is either side ok?
In the case of installing a helicoil at the far end of a through- threaded hole, there is some risk that the helicoil will screw itself out of the far end as the mating bolt is inserted and screwed in, so the helicoil probably should be installed just a little shy of the far end, and retained by staking the thread so the helicoil is trapped.
Or tap the hole not quite all the way through.

you may want to try a few test, then make up your mind.
I am with Mike on this one. I believe this can be a problem.
I have had helicoil's physically unscrew.
