For bolt on I would use something like this

and have a solid plate behind it sandwiching the bumper material. This will help prevent the bolt heads from pulling through. Might be overkill but better safe than sorry!

And I am pretty sure you said you were doing so but just incase...high quality grade 8 bolts ONLY!
Shoulda coulda woulda....I went with bolt on type, grade 8 bolts, not sure if I need the plate on the back, the wall thickness on the tube is 3/32", that is some pretty thick stuff. I do have about 3/8" of bolt left, so I may add it later.
