Message received guys, thanks. I am looking for a machine shop to neck down the
threaded portion the entire lenght of the bolt. then I will have a bolt welded
to the bottom of the anchor using the old bolts. This should solve any pullout
concerns as this mimics the original bolts, just shorter.
Next, I am still having the concern about the oversized hole from a material
strength perspective. I am still trying to get an answer if quikrete or some
other anchoring cement is good enough in terms of sideways strength. My
understanding is that the compression strength of the material has to greater
than the lateral (shear???) strength of the bolt. The idea being that you want
the bolt to be the weak link and not the concrete surrounding it.
