Old Guy, if you're answering this, thanks for the reply on my problem with the concrete setting before the anchor bolts were in- UGH! Anyways, you suggested using "expandable" anchor bolts. How do these differ from ordinary J-bolts, etc. Thanks again for reply!

It's an expandable ANCHOR, not a bolt. (It's totally different from a J-bolt.)

Here's an example of one, but they come in different sizes.
It is a lead anchor that is made to accept a separate lag bolt by screwing the bolt (steel) into a softer (lead) metal, and it expands against the concrete hole to hold everything in place.
It is tapped (with a hammer) into mortar or concrete holes pre-drilled with a masonry bit.
You can use a threaded wood screw-type lag bolt to bolt whatever you're trying to hold to it.
Go to your local hardware or big box store, and they can show you.
(By the way, please stay on the same thread when you're on the same subject..it is much easier to follow.)
Good luck!
