Terminating Flexible Metallic Conduit

I am trying to terminate 1/2" FMC into a box (attach a fitting to it) but am having some issues. I've tried using the screw in connectors but I don't really like those. If I put them on hand-tight, they don't feel secure enough and if I tighten them with a wrench I seem to over-tighten them and it breaks loose. There doesn't seem to be a happy medium because it feels like it will pull out or come undone if the FMC were to twist in the direction of untightening.

I've also tried the squeeze type fittings and I don't really like the way those work either.

What am I doing wrong?

I personally like to use the set screw type connectors like this: E_18 There are many brands out there that make the same as the ones I listed. These fittings are only for use with steel flex conduit. If you are using aluminum conduit then you can only use the squeeze or screw in type.
