CONFAST 3/16" x 1-1/4" Blue Flat Phillips Concrete Diamond Point Screw Anchor with Drill Bit for Anchoring to Masonry, Block or Brick (100 per Box)

Screws hold in brick just fine. The included drill bit also works, but you must use a hammer drill. A standard drill will not get the job done.

Good product

Very good item. Excellent choice for my project

screws good drill bit bad, took forever to drill a few shallow holes. If you already have a tapcon drill bit then these are a cheaper alternative.

My husband used these for hurricane shutters

Just finished installing about 50 of these into a poured concrete wall and not a single broken screw. Only two screws "spun out" and didn't grip the concrete, once where I was repeatedly trying to drive it deeper so the head would sink into the wood. The other was a hole where I hit rebar and had some trouble drilling the hole, probably not the fault of the screw.If you are using these flat heads to avoid the screw head from protruding from the wood, you will definitely want to use a countersink bit in the wood you are attaching to the concrete. I went with a slightly oversized half inch bit and it worked perfectly for me. Without it, the head will protrude and trying to force it deeper will cause the screw to spin out as I mentioned above.I didn't try the drill bit that came with the set, instead using a Milwaukee MX4 bit with one bit surviving the entire project.

No supplied drill bit in my box

The screws arrived on time. They worked as needed to install a form around a CMU wall.

Way cheaper than the local hardware stores. I ran short and had to buy some extra locally. Out of the box of 100 that I bought from Amazon I broke or stripped about 8. Out of the package of 25 I bought locally I broke or stripped 15. The Amazon ones are way better quality IMO.

It is very strong and works excellently.
