I use these in my barn to attach padding to the cement walls. They need a pre-drilled hole but that's to be expected. Once I got the pilot hole drilled these screws went right in. I haven't had one shear off so far. Overall a solid cement screw at a price much better than the big box.

I have been using these to secure framed walls to my basement floor after I ran out of the big box store brand. So far these has performed exactly the same, you still get a couple that will shear off which is to be expected for this type of screw, especially if you send them a little to hard. I have not used the drill bit as I used an SDS to drill the holes. Overall cant complain with the same quality for a lot less money. I would recommend.

So this is partly my fault. I used the bit that came with it and foolishly drilled all 12 of my holes before testing. THe size LOOKED right. It was not at all. It was a 1/4", a FAT 1/4" bit! This made my day a lot longer. I could either go get a 5/32 bit long enough for these or just go to lowes and get 1/4" screws. I did the latter. So the screws seem well built and the bit that came with it is ok, just don't be like me and measure first. Save ya an hour and an extra $25.

Product: Bonost 100Pcs 3/16×3-1/4'' Concrete Screw AnchorThese are very good concrete screws for mounting wood or other materials to concrete which is what I will be using them for. They are log enough to mount 2x4's to either concrete walls or slabs very securely. I am in the process of building concrete column forms and will use these screws to securely hold the forms in place when pouring. The quantity provided is more than enough for several projects and you can re-use them if you don't need to leave them for a project. A 5/32" (not 3/16") hole is required for these and there is a drill bit included (I didn't find it until I took all the screws out of the container to count them). I like using my SDS Plus drill for this task, so I bought an additional bit which was longer.These look to be good quality and the relatively inexpensive which makes them a very good solution. I would recommend these screws.

I have an area in the driveway where I set up a portable garage (tent) for working outside sometimes. I installed 4 tiedowns so I can ratchet the framework to anchors I put into the driveway for stability in windy conditions.They have worked well mostly - but 2 times I have broken the bolts.When installing into bricks with a small hammer drill, I sheared off one of the heads when attaching my flag holder. Once it got tight it just snapped off when I tried to get it tight. The other 3 bolts on that install did not snap off and are still holding.Then, I had one break off both bolts when a tie-down I had installed was hit by a skid-steer tractor the other day. It popped off quickly and, while I'm not sure of the force that was applied, it seemed to come off very easy.I have some other projects I will be doing and, as mentioned, they do seem to hold well when not over twisted or hit with a side force. I only marked them down by 1 star as I haven't tried other types to see if they do better.They are easy to install and stay secure for what I needed. I just have to replace the one tiedown that got sheared off. Not bad overall.

You can’t really torque these down properly or they will break off quite easily.

These are a very secure fastening method, but the masonry bit needs to fit into the chuck plus drill 1/2" deeper than the screw length. A longer bit is needed. For precise positioning, drill right through a board and into the masonry. For best hold, place screws in solid masonry or concrete - not a mortar joint or well of a block. It is important to choose the correct length, diameter, and head design for the job. For longest masonry bit life, use a hammer drill instead of conventional, and clear dust from the hole regularly as you drill. Don't overheat the bit tip, or the brazing will melt and the carbide will disappear. Chances are that you will need additional bits to drill 100 holes. Save the literature, because the correct bit diameter is critical to screw holding power. It is a special, odd-ball sized bit.

Very pleased with these screws. They make for a solid hold into concrete. They come in a handy clear plastic box for storage. Included the necessary drill bit, that was a nice bonus. I wouldn't plan on the bit lasting for the whole box of screws, but it will be good to have until it needs replaced.
