These are excellent concrete screws but they have on negative issue that prompted the loss of one star. These are carbon steel coated with zinc, which makes them very effective at bitting into concrete or brick. However, when screwed in, the zinc coating is partially removed and the carbon steel that remains can rust. Hence, I only recommend these are dry locations and preferably not ground anchoring. If used in such circumstances, it is best to add a coating of silicon sealant.

These are good tight screws that go in easily and hold on tight. They come with a driver bit for fast and easy penetration. Be sure you use the proper sized hole.

I was a little concerned because it seemed like the screw was not going to fit into the 1/4” hole I drilled. But once I put the ratchet on there it went right in with little effort. Holds strong, and seems just as good as those name brand blue ones. Good value for the price. I like them.Five stars.

These are absolutely fantastic concrete bolts. They have very very aggressive threads on the bolts, with the lower threads even being serrated like a knife blade. The flanged bolt head is WIDE and will hold anything down. The washers are just OK, and seem a little thin, but I look at them as a bonus due to the nice flange on these bolts.The 19mm nut driver this set came with looks fine (I used my own impact socket) but I did note during my testing that the nut driver is magnetic in order to hold the bolt in place. Buuuuuuut the magnet isn't strong enough to hold these bolts and will just drop it out if held vertical. Not a major deal, but just an FYI for those who like to know that stuff.Other than that, outstanding build quality and a nice pack of washers to use at a later date.

These 20PCS 1/4" x 2" Heavy Duty Concrete Screw Bolts are fantastic! They’re super durable and provide a strong, secure hold when anchoring to brick or block. The zinc plating ensures they’re rust-resistant, and the included washers and hex socket make installation easy and efficient. I was impressed by how simple it was to get everything in place, and these bolts hold up really well under pressure. Great quality for the price—definitely recommend for any masonry projects!

Wow, these concrete anchors are gigantic.They are much bigger, heavier, and sturdier than any other concrete anchor I've ever used. The nut driver included with them is nice, but I doubt you could get the necessary torque from the small cordless drill it would normally attach to. You're going to want an impact driver for this.

These concrete bolts install and work as well as Ta***n style bolts at a much lower price, making them a great value. I give them 5 stars.

These are big and heavy anchor bolts. They are intended for permanent installation, and are not recommended for re-use because the threads can get worn down with a few installations. Be sure to rinse out the concrete dust from the 1/2" hole before installing.
