These huge concrete anchors can hold virtually anything! Perfect for most masonry applications. I like these because it is easier to install than other types of anchors. They are rated for indoor and outdoor. If you need to install some wood framing on concrete, this is definitely the way to go. It gives you the confidence to mount anything on your walls when you use a high quality, durable anchor like this.

Tapcon 1/2 in. x 6 in. Hex-Washer-Head Large Diameter Concrete Anchors (2-Pack) review: Tapcon makes GREAT products for securing anything to concrete! I have used them before and they always get the job done. This set is, IMHO, BIG concrete screws! Wow, I have never seen a concrete screw this large. You will need a rotary hammer drill to drill a pilot hole into concrete. Then, you will be best served by am impact driver to slam these puppies in! Be sure to drill the pilot holes about a half inch deeper so that concrete residue falling into the hole does not prevent full insertion of the screw. Also, BE SURE to vacuum out the hole in the concrete after you drill the pilot hole - VERY important. Love Tapcon products! There ya go!

Robust and simple. These anchor bolts mean business. They are not just scaled up version of smaller ones, but have been carefully designed to anchor themselves into concrete. First thing to notice is the tip is not designed to drill its way into concrete, you have to drill a hole first and the packet tells you exactly what size masonry bit to use. For these 1/2” bolts one needs to use a1/2” drill bit. The packaging goes on to also tell you that one will need a 3/4” driver to screw the bolt into the hole you drilled and the maximum torque of 70 ft. lbs. The threads on the end are slightly tapered so that the bolt can be started in the correctly sized hole. The underside of the head has small ‘flutes’ to prevent it from unscrewing. The 4” length is from the tip to the underside of the head. They suggest drilling the hole ½” deeper than the end will end up, i.e. 4 ½” less the thickness of whatever you are bolting down.

I have never used Tapcon before; heck, never heard of them before I started my project. I did some research, looking at ways to anchor safes to concrete floors and determined this product was pure genius for multiple reasons. The biggest is they are 100% reusable. The wing anchors are fine, but that wing ain't coming back out. Same with the anchors that use the sleeve that goes in the hole to secure the bolt. (Also, I tried this one before and had mixed results. Also, in my case, my application required that I drill all the way through the floor, so that little sleeve might just drop through.) Lastly, in the case of the anchors with the sleeve, you have a nut that goes over the top to secure the safe. In my case, I would have to figure out how to cut the top of the bolt off so I could put the cover cap over the hole in the base of my safe. (It's a safe, but no need to be barbarians here. The caps make it look clean and neat.) Enter, Tapcon. I drilled the hole, cleaned it out, then put in the Tapcons. (One site suggested a socket wrench, but that would have taken forever. My impact wrench worked wonderfully.) The safe isn't going anywhere until I say so, and when I do, I just move it, drill more holes, and put the same Tapcons back in. This is the way it should be!
