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 screws set comes with the exact size drill needed. No guessing for a correct drill to use, and no more having a hole to large to hold. Once you hang whatever into your concrete wall, it will stay.

I purchased to repair a down spout that had fallen off the house. The enclosed masonry bit worked well in my hammer drill. Screws went in the holes without a problem.

Used these to hang small hooks along the brickwork outside the house.

VERY S-L-O-W-L-Y, and with water to keep the bit cool. I didn't know better and fried it, got another (and some advice) locally and voila: screw worked great.

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.

It worked great once I found the drill bit inside. The instructions on the package are very small, having a larger font would have helped me a lot!

I would highly recommend these screws for concrete block applications. Very strong and effective.

Used these to hang a towel rack into my stucco/block house. They worked well seem solid and came with a drill bit to pre drill the holes which is super nice. Definitely make sure you have a hammer drill for drilling the hole out. A fraction of the price of normal tapcons!
