My gun safe was delivered yesterday via the purchases freight carrier and my brother and I horsed it into the basement with the help of my skinning winch in the garage. I followed the instruction for bolting it down to the letter: drilled out the fireproof caulking with a 3/8" bit and continued through the mark the holes, moved the safe out, drilled the holes with a 7/16" bit, dropped the plastic anchors (http://www.alibaba.com/product-detai...519083866.html) and bolted the safe in with the washers and included lag bolts. The problem is it never seemed to tighten up. The bolts grabbed and smooshed the gasket on the washers but never fully seated. I'm thinking I'll put a few washers on the lag bolt and see if they grab better in case they are bottoming out and if that doesn't work, pull the whole works out and replace the plastic ones with lead anchors.
Has anybody been down this road before and dealt with something like this?
