Rated 3.9 out of 5 by 9 reviewers.
Rated 3.0 out of 5.0 by Not bad Their instructions tell you to drive the screw into the hole with a bit in a hammer drill. I have found that any kind of power driver may cause you to strip the hole. I have better luck using a hand driver. I've stripped to many holes to give it a real high rating; maybe with practice I'll get better at it. April 5, 2014
Rated 5.0 out of 5.0 by Excellent Product Great product and the drill bit is not a cheapo, It is very sturdy. December 20, 2014
Rated 4.0 out of 5.0 by Work Well The only time I've had problems with these stripping out the hole is when I've been too enthusiastic running them in with my cordless, which I only fault myself. A little finesse with the power tool, or screwing them in by hand, and no problems. April 28, 2014
Rated 5.0 out of 5.0 by Quick Concrete Anchor I'm installing some label plates on the floor for product identification. All the screws did great. Then went to install some plates on the outside of the building. Only had 1 screw not grab well but as I was drilling, the Scissor Lift moved a little and caused the hammer drill to move a little. That can not be blamed on the product. Yes, I'm buying more of these in various sizes for other projects here. Works best for me with a cordless hammer drill and a cordless impact to run the screw in at lower speed. Real fast. December 4, 2013
Rated 5.0 out of 5.0 by no fails I've been using these for 3 years now (since I knew they existed) in multiple sizes & media & haven't had even one work loose or otherwise fail. July 22, 2014
Rated 5.0 out of 5.0 by Great for screwing to block Worked very well for attaching furring to block. Make sure you use a hammer drill though. December 23, 2014
Rated 2.0 out of 5.0 by good idea--poor execution I used the enclosed bit for the hole, but had 5 anchors shear off. Great idea. My box of product was poorly made and didn't perform to expectations. March 22, 2014
Rated 1.0 out of 5.0 by tapcon Included masonry bit drills too large a hole for screw to bite, just spins in hole. TERRIBLE results. in my situation, this product has cost me hundreds of dollars on a colored concrete repour. July 26, 2013
