I'm talking about an anchor like this only not necessarily that size.

I think the issue is the holes in the plate are smaller than the holes he needs to drill for anchors.

So my thought would be just drill the plate holes larger.

Use a larger washer on the anchor bolt.

But then does the plate need to be sandwiched between the anchor and bolt?

Not a mechanical engineer but logic says if sandwiched the plate helps spread load?

As in if the anchor fails it can still pull through the plate?

Honestly, I'd not be worrying to much about it.

If it's too large and heavy to move without equipment is it really going anywhere?

What value do the anchors provide at that point?
