304 Stainless Steel Expansion Anchor Eyebolt Screw Open Cup Hook 5pcs (M8 Eyebolt)

Muy buen producto

Works well and holding up like champs.

The anchors themselves are great, but let's talk about the 12mm masonry bit it says it requires. I got one and made a hole that was too small. I used a 1/2" (#12) bit and even had to bore that out a little to get them in. The 1/2" bit did take out a little of the opening, so one nut is nearly in the hole, but I could change that. The point is that it won't fit into a 12mm hole, so if you already have a 1/2" bit, that is what you need. I've used it on 4 of them. Other folks have said that's too big, but that is not my experience, but not saying it won't work for you. The eye doesn't fit flush with the cement and a good amount (3/4" or so) of the threads are visible. I saw no way to tighten it and keep it in the hole at the same time. Tightening it raises it out of the hole and/or lowers the nut. I'm using it on a concrete patio to tie down the roof with a cable (Florida hurricanes). This is my first time, so I may not have done it correctly. I just wanted something that won't come out.

These worked great holding items secure in concrete. Easy to install and use. Highly recommend!

They work Great!!! BUT YOU NEED A 12 MM DRILL BIT. Buy the drill bit when you order them! I got one and they went in well. 3/8" and 1/2" bits don't work very well at all.
