I don't know that they are adequate.
A number of previous posts address this. Try a google search for "short anchor bolts site:

One solution: Elocone nuts.

A half nut will have far less than half the tension capacity. It may be as little as 25% by the time lead-in chamfers and incomplete threads are accounted for. I like the approach for the elocone nuts.
