Hey guys, happy black Friday. I'm asking if any of you have used this type of concrete anchors and how well they held up

Never user a concrete anchor that looked like that. The ones I used expand when you screw them in.

Depends what you are fastening, and how many anchors you use. If a light fixture, probably fine. For something like a safe? I would rather use a expansion type anchor. The longer the better. 1/2" bolt size minimum.
O btw i am a plumber. We use anchors on almost daily basis. Another option is drop in type. The bad thing is you need a special tool to "set" the anchor.

I use Redhead anchors. What OP posted looks like a lag screw. That would work securing your safe to a wall but not effective when anchoring to the concrete below.

I have used them and they work great but you need a BIG impact drill/gun to get them to work properly. Used the right way and it will crush a 2x4 with ease.

I was talking to a buddy at work yesterday, he mentioned a impact gun too

This might be a better bolt. I like the idea that they can be removed easy

Looks like the same, just make sure when you drill the hole in the concrete to clean it out good or you'll have a tough time tightening it all the way.
