They gave examples of buildings, bridges, and several mechanical items including lawn mowers and cars that had killed people due to screws and bolts that had failed when they shouldn't. If nothing else, I at least plan on getting the biggest size available of the same type I already bought.Ĥ50 lbs sheer from Lowes.I ended up breaking one of the bolts as I was tightening it.Ībout 20 years ago 20/20 did a story where they claimed the Chinese were trying to destroy the US economy by shipping inferior fasteners that were sold in US chains like Lowe's and Wal-Mart. What's the best type of anchor to use for this application? It looks like the kit that is sold (at a huge mark-up) by the makers of my safe includes drop-in anchors with the set tool. I want to be able to have the safe solid and not have to worry about someone getting leverage and ripping the anchors out of the floor by pulling on the safe. So I was able to get all the anchors out of the holes along with the broken bolt. Obviuosly that's not the way to set it up to be secure. I didn't want to tighten the bolts too much as not to break them. I didn't try, but it almost felt like I could rip the safe out of the floor if I wanted. I cut through the carpet and pad around each hole before I started drilling into the concrete. The three that remained left the safe wobbly. I could see some of the concrete dust inside the anchor after pounding them in. I think it was because I didn't clean the holes out good enough. Anyway, I ended up breaking one of the bolts as I was tightening it. As I was drilling, I thought the bolts were way too small, especially based on the size of the holes in the bottom of my safe. The hole I drilled for each anchor was 1/2". I originally bought some lag bolts/anchors for concrete rated at 300 lbs tensile, 450 lbs sheer from Lowes. I want to anchor my safe to the concrete foundation.
