3/16" x 1-1/4" Concrete Screws, 100 PCS Blue Hex Washer Head Concrete Screws Anchor Kit with Drill Bit and Hex Bit Socket, for Masonry, Cement, Block, Brick or Stucco

50 screws, with bit and nut socket... All for about half of what Tapcons are. I call that a great value.I used a brushless DeWalt hammer drill, and using their bit, it drilled pretty easy. I used the screws to fix a 2x6 to concrete for framing and I was worried about how deep it would go. It countersunk to flush with no problem. These are great to have on hand.

These are on the large size for the projects I had going, so I wasn't able to use as many as I thought I would. That said, they are exactly as you expect. Hammerdrill out the pilot hole, screw it in.This size, 1/4", is too wide for Ring security lighting bases, in case you were wondering.Works like a charm to attach pressure treated lumber pieces to block/slump walls. Then you can use the included screws with the Ring security stuff to attach to the wood.
