These are drilled into my concrete wall to add a rock climbing wall. The bolts held and did not break even with some serious torque. But the drill bit ground to a nub pretty fast. I had plenty of hammer drill bits to use instead.

Work great but drill bit is a little lacking in length.

These work well. Like them much better than red heads that can be problematic at times. These are a straight drill and drive them in. I found an impact driver works best when screwing them in.

What I like most about this concrete screw set is it came with everything needed for correct installation. All you need to add is a descent vibratory drill and some muscle. The drill bit included is the correct size as is the 1/2" drive socket. Personally, I seldom need to drill concrete to anchor things to or attach items to concrete, but I stand ready for the opportunity.

These concrete screws work great for attaching a gate to a block wall.I'll update this review if there are problems in the future.

Great fasteners. No issues with them. Fast Shipping. Only thing was they sent me the wrong size socket and drill bit, sent 3/8 instead of 1/2. No BIGGIE I have lots of them.

These screws were not of my liking, I used the same drill bit that I used for another same size brand and these were loose in the concrete holes, I didn’t return them, and didn’t use them all. Once I finished the few holes I had left I just put them away and I’ll see what I can apply them to.

I was anxiously waiting for these to arrive so I could replace the anchor for my wall mounted water hose reel. These were larger than the hole in the reel, but metal holes are very easy to enlarger vs drilling from scratch.Used a drill bit for metal that was slightly larger than the bolt to enlarge the existing hole in the hose reel slightly. Then switched out to the masonry bit supplied and match drilled/enlarged the hole left by the failed anchor into the brick. That was also an enlarging operation and also went quick and easy.The bolt looked to be longer than the thickness of my brick, so I used the drill bit to verify that the bolt would not bottom out before it was tight. I had a good 1/8 of an inch to spare. Make sure to check or the bolt my push the brick wall out from the house frame and cause a disaster.Inserting the bolt was done with the supplied socket (metric) on my 1/2 inch ratchet. The threads on the bolt quickly cut matching grooves into brick and went in VERY easily. I was actually worried that the threads would stripout before thightening up. That didn't happen. It when from easy to turn to tight in less than a quarter turn.I pulled with about 100 lb of force on the hose reel and there was no detectable give at all.These are so much easier than the concrete expansion inserts that I've used in the past with lag bolts.Even though I'm a Vine reviewer and get these for free, I'll be buying some more of these in different sizes.The supplied drill bit also has a splined end that doesn't allow the bit to slip in the drill chuck.Hope you found this helpful.
