1/4 x 1-3/4 Inch 50Pcs Concrete Screws, Hex Head Screws Anchor with Drill Bit, for Masonry, Block, Brick, Cement, Stucco, Diamond Point

They worked very well. None of them broke and I drove over 60 screws. I will buy again. I hope this is helpful.

Nice price and they did exactly what they were supposed to do

I had bought some concrete screws at a big home-improvement store, but the ones I chose were too long. These were just the right length for my project. Also, I screwed all of them in with a 5/16" socket and ratchet - the original ones were very prone to having the socket twist off, but these were far more grippy. It's important to thoroughly remove dust from the drilled hole - in one case I did a poor job and the screw snapped off. Otherwise, I'm quite satisfied.

Strong and reasonably priced. Comes with suitable masonry bit that does the job. Would buy again.

Just as good as the big name at a much lower cost! Used the included drill bit to create pilot hole into basement wall, and securely mounted pipe brackets without issue.

Needed these to install a garden hose hanger into my concrete dug well. Great value, they give you a bunch, quality is great and they perform like they should. Recommend making sure you drill far enough down the bit doesn't bottom if you do they will break. Otherwise easy to install, the added drill bit works perfect.

I like that they were in a case & I used them to support shelves on a cinder block wall.

No deformities, accurate enough to trust repeatedly. Alloy seems conformant to standard.
