These work amazingly well for attaching things to mortar and concrete. They are a huge time saver and in some instances work better than masonry screws, certainly quicker.

Where have these been all my life? Far better than any other concrete fastener I've used--the next best is a distant second. Honestly, I don't understand why they work so well. I expected them to have good vertical strength, but not much horizontal strength. I used them to mount furring strips over 2" XPS insulation. The concrete walls are medium quality, built in 1960. I had to be careful to keep them from clamping down the furring strips to the point that it sank into the XPS--that's how much horizontal clamping power they have. And oh so fast to install! I was giggling each time they went in so easily. I'll never buy another tapcon.

Just like others, used this on basement wall to attach 1x3s to 2 inch XPS insulation against basement wall. This has worked perfectly. This old house video on youtube shows how.Best reason for doing this is when you want the extra inch or two of space by not framing the area in completely, and your basement walls are pretty straight to start off with.

Work great. I had trouble with screws just pulling the concrete out of the hole and stripping, these press outwards and use friction. They hold very well but are still removable with a claw hammer if need be.

Bought to secure 3" XPS insulation to basement concrete was, but they turned out to be too short. Unfortunately, couldn't find any longer ones of this type.

I used about 200 of these my basement to install 1"x3" lumbar over rigid foam insulation against the foundation. They are strong and very easy to use.Few tips:1. Drill a hole at least 3/4" deeper than the anchor.2. Use a decent heavy sledge hammer to drive them in. It will save you lot of frustration and hammering. I used a 3lbs hammer that drove these anchors into the concrete very easily.

Like a number of other commentators, I was turned onto these things by a video post from The Old House on how to refinish a basement. They suggested using these squiggly bolts to hold lathing and foam boards snug against a poured concrete wall. They work exactly like they guys said. Fast, cheap, snug and kind of satisfying to whomp them in. My dog doesn't like the noise of both the drill and the hammer. As others have said, don't bother with a regular hammer, use something heavier, they need a hard whomp. I do use my regular hammer to tamp the bold through the lathing until they hit the hole and then switch to the whomper.

After working with tapcon screws, these are much better. I'm doing a basement remodel, and after breaking a couple of tapcon screws, I decided to buy these. Surprisingly, they came the next day along with a dewalt drill bit that I ordered at the same time. Using a hammer drill, I drilled the holes to the desired length, and then pounded the spikes into the holes. Every one went in properly into a poured concrete floor, as well as a concrete block wall. Highly recommended.
