Since we don’t know the strength of the material, we can only reference (2) documents for your use. These documents outline conditions such as spacing requirements, etc. to get certain loads. 1.

1/4 in. x 3-3/4 in. Phillips-Flat-Head Concrete Anchors (25-Pack) is rated 3.5 out of 5 by 2.

I drilled the recommended size hole to the recommended size depth and you couldn't get the screw to go all the way in. Either they would break or strip the hex head. Try the flat head? Good luck with that! Flat heads don't work that well with that kind of torque needed. One of the screws I got to about 1/2" before going all the way......soooooo close!! Oh well. Guess I'll try lag shields and bolts.

Rated 5 out of 5 by from Excellent Anchors, Don't Break I used these to put 2-inch XPS insulation around the wall in my basement. I cut notches in the insulation and inset wood strips, so I ended up with a flush surface. I used a DeWalt impact driver to set the anchors. Out of 150 anchors I didn't break any, even though I was driving them into a poured concrete wall. Admittedly I only drove them 1-3/4 inches, but I still didn't break any of them. I learned a few things. That main thing is not to let your drill bit overheat. I broke the first bit within the first ten minutes when I was determined to put an anchor in a particular spot and overheated it. Then I got a small can of water and after every eight or ten seconds I dipped the bit in water. It lasted through the rest of the project. The next thing is to not get determined to set an anchor in an exact spot. In my case, I could tell when I ran into a large stone within the concrete. Trying to drill through the stone was difficult, and setting the anchor through the stone was next to impossible. Just move over an inch or so and start over. Unless it's absolutely critical that you get the maximum holding strength out of the anchors, if you can't drive them the full depth, instead of driving them until they stall or break, just beat them in the last bit with a hammer. Works great. Overall, I'm very happy with the end result.
