1/4" x 2-1/4" Concrete Screw Anchor, Blue Flat Head Screws for Anchoring to Masonry, Brick, Block, Cement or Stucco (Pack of 30)

These are nice! They work great on concrete, but also in my experience work great for wood too! I would say since the screw grooves are finer to the base they stick firmer than dry wall screws! Just a bit of advice.

These worked perfectly and they came with the bit! I'd say these are at least as good as as TCON in quality and durability. I used most of the pack and didn't snap any off! They went in and the bit depth was perfect.

Excellent Product.

If you’re only needing one, if your lucky 2 holes drilled out you’ll be ok. Have your own reliable drill bit to do anything more. The screws work. Very reliable.

I bought these after looking at the Tapcon brand. I wanted a smaller quantity but longer screw, and the big box store brands only offer large quantities in the size I needed. So I took a chance and ordered these. All I can say is, thank you for offering a product of equal quality but better value than the big brands. Not a single screw head snapped, and every screw grabbed in its predrilled hole and held firm. I’ll be buying more of these for sure!

I don't think I've ever written a positive review on screws. I was hesitant to purchase masonry screws with a flat Philips head, imagining rounding them out. My driver struggled a bit to drive some of the screws in old, dense brick. None of these screw heads slip out even once. I even drove one in which the hole was a tad short, being too lazy to go down the ladder and retrieve my Makita Hammer Drill. Using my Makita Driver and Phillips bit I managed to screw it in using max torque (20), and the screw did not slip. This is my first purchase of this brand and I'll be looking for this brand in the future. I also like the convenient container and the 5/32nd masonry drill bit as a bonus. As you can imagine, the bit is not superior quality but it drilled straight and true and finished my project after the one from another brand quickly crapped out.

Excelent product, recommended.

The drill bit that comes with this kit is bad quality. The screws however are great. I had to go to the store to buy a better drill bit. Once I did that installation on light boxes on my stucco house was a breeze. The bit that comes with it would not even drill in more than 3/8 of an inch. The one I bought from store went all the way through like the wall was butter. Once I drilled the holes with the better bit, the screws installed perfectly. They hold extremely well. Just make sure you buy the exact size bit required for your screw. If you buy one too big it won't work. Too small, it also will not work. Has to be right on the dot. Having said all that, I still think this kit is worth it. For the price you pay here, you get 4-5x more screws than you would for the more expensive brands at the big box store.
