Don;t know what they are called or where to get them in the US (I assume you
are there).

See this:

Basically, you dill a hole, 3/4 fill or so with special polyester or
vinylester resin and ram a length of screw stud in, leaving enough sticking
out to hold thing being fixed and add a nut. When set, add thing and do up
nut - job done

Very very strong and places minimal stresses on the substrate. Quite good on
unstable crumbly substrate too - they make special resins if you have very
poor concrete/block.
