Tie rod Turnbuckle connection 2

[honat]

I am doing an analysis of an existing structure that has a tension rod with a couple of Type 1 open, form 1 turnbuckle body forged in this tension member. The connection at the turnbuckle head shows no thread projection on the rod as should be expected. My question is: Is there a minimum Thread projection requirement in this type of connection? If so what should it be? Where do I find the specification on this matter? Thank you

You can try some of the manufacturers such as:

I have always understood that there must be some length of screw thread protruding into the body of the turnbuckle to ensure the full load carrying capacity is developed.

Flush with the end is fine, no excess is necessary.
