The hold up was due to the struggle over 'where' its permanent location should be...once I worked through that it just became a project to execute.Zonie said:Glad to hear you decided to 'nail it down'.
I'm not sure what size the thru bolts are but even if they are only 5/16 diameter, if they are made out of a good hardened steel, each one of them will require a force of over 9,000 pounds to break.
That effectively gives your safe a "weight" of over 37,000 pounds before someone can lift it.
I went with good sized 1/2" x 3" RedHead anchor bolts.
I doubted that the concrete pour for the garage floor was more than 3"-4" and I didn't want to drill deeper and risk punching through that would let moisture come up into the bolt holes.
