Four (4) 1/2" Inch Premium Zinc Plated Carbon Steel Knurled Drop in Anchor (BCP1001)

These work great. Good quality and worked exactly how they were supposed to. We used them to anchor and very large and very heavy tent to concrete and had no issues.

Drilled the 5/8" holes in cement just deep enough so they were just barely under the surface, used a smaller bolt and a heavy hammer to 'set' them by beating the plug in them down hard. It was easy and they seem to be sturdy! Using for my harbor freight tire changer.

Ordered 4, one was defective, would try again

Just make sure to get the holes straight when you drill them, and make sure to tighten bolts down really well so that it expands these anchors. I mounted a manual tire machine from HFT on the garage floor, and then I bought some carriage bolts and cut a slot in the top so I can use a screwdriver to tighten them up. Those are not the bolt normally use, of course! I’m just using them to cover up the holes so I don’t get garbage in my anchors while I’m not using my tire machine and there’s not an exposed hex bolt head to trip over like if I used regular bolts. When I want to use my machine, I take the carriage bolts out with the screwdriver, put the machine down, and tighten it down with the real bolts. Anyway, these anchors have been great.

I used these to mount a manual tire changer in the garage. Now I can bolt it down securely in an area with plenty of room to work, and then quickly unbolt it and move it into a corner when not being used. The toughest part of the installation of the anchors was drilling, but a good bit and hammer drill will get the job done. I bought the tool to install anchors and it was easy to hammer them in place securely.

I think this product is awsome

Bolted my tire change machine to the garage floor with these ~ it isn’t going anywhere

Trying to install a manual tire changer in garage floor. When tightening the 1/2" bolt into it the anchor broke in two when it was down in the drilled hole.
