IIRC it is possible to get a polyester based adhesive for fitting studs into
concrete.

Both yourself and The French's suggested anchor bolts.

Correct me if I'm wrong, but I thought these were like metal rawlplugs

concrete to have enough torsional strength to hold them in place. In
short,
I would expect to tighten the bolts and have the anchor bolts split the
concrete into two chunks.

If anchor bolts are something else, please fill me in on how they work.

AFAIK, that *is* what the are, and if your concrete is indeed only 4"
wide, then it would almost certainly split.
