230x Phillips Flat & Slotted Hex Washer Head Concrete Screws 1/4″ and 3/16″ Blue

To be honest, I did not have an immediate need for these, but I've had to buy similar in the past. When I saw these for a great price, it seemed like a good time to get them. Let's face it, 200 pieces for about $24 is only 12 cents per fastener. Immediate use or not, I did test them. There are 2 different diameter sizes in the set, so the set includes two different masonry drill bits, which powered into a brick with no problems at all. I then used an impact driver to sink one of the screws into the pilot hole in the brick. Since my test brick was not embedded into a wall, I half expected it to split the brick, but it drove in quite nicely. I have an upcoming project of repainting and reattaching shutters to the front of my house, so these will be quite useful.

Concrete screws… they’re blue. Nice variety. No problems. World buy again.

Work very well

Several different sizes. You never know when what you have may not fit. Here you have several sizes that may fit your task. Don't run off the hardware store when starting a job. Can't go wrong.

Anybody who buys this knows what they're for. I'm tired of paying a fortune for tapcons when I only use them once in awhile. I live in Florida so periodically need a stash of screws to use with my hammer drill to attach anything to the my house. This is a good set, seems almost as strong as tapcons and very good price. This set will last me forever and give me plenty to give out to neighbors when they're also borrowing my hammer drill.

I simply find life easier when you have a mix set of something like this, you never know when you're going to need it, and this way I have it.
