Customer Reviews for Tapcon 1/4 in. x 3-1/4 in. Hex-Washer-Head Concrete Anchors (8-Pack)

So I installed these per the spec into my concrete patio and they pretty much just got torn up. I drilled the correct hole size, cleaned out the hole and tried to drive these in. I had one completely sheer off and on Atleast half of the others the threads just got eaten up. So for Atleast on concrete I'd avoid these, they may work better on brick but I haven't tried yet.

Very good anchor especially for concrete did the job effortlessly.

great product.

These are junk. I was using to anchor a toilet flange to a concrete slab. I pre drilled the holes with the recomended bit, to slightly beyond the depth of the full length of the screw. I then followed the directions and used a hammer drill to install the screws. No matter how slow, or how gentle the touch on the trigger, the screws all broke (6 to be precise). I then used a short handled socket wrench, achieving the same result with 4 more. I'm no stranger to the dangers of over torquing a bolt or screw, and these all snapped when they should not have. Now, adding more time to my project, and if i cant find a better solution, potentially costing me a lot more money than these fasteners retail for. Very disappointed. I wont be buying them ever again, and hopefully Home Depot takes them back on return.

Quality at it's best, these anchors stand up to the test. They don't break very easy at all in fact I haven't had one break yet, just the drill bit. With the proper depth drilled these anchors helped support the foundation and didn't slip or spin out

These were the correct length and worked great for my needs in attaching an electrical box to an interior concrete wall.

They work as intended for anchoring into concrete

Hex concrete anchors worked perfectly with the masonry drill bit so that the fixture was attached to the cinder block where the hole had been made.

Drill bit as advertised and helped me install the shelf for my wife.

Excellent anchor for holding metal to concrete floor. Would buy again.

Easy to apply on concrete block .

Good product but doesn't meet the weight that saids in the description, this can used for light works

Easy and provides a secure hold.
