Absolutely great anchors for the price and they also include the proper size carbide bit for the screws. They may not have quite the holding power of Tapcons since the threads are not as pronounced, but for my use they are just fine. I can't budge them loose with a crow bar so that's good enough for me.They are also corrosion resistant plated which is good for use when anchoring treated lumber. Overall a fine anchor screw that I'm quit..
