1/4" X 2-3/4" Heavy Duty Stainless Steel Concrete Anchors Eye Bolt Eyebolt Anchor Wall Concrete Brick Anchor Expansion Bolts Ring Screw Eyes,5-Pack

Ordered these for tying down the Car Port at our FL Manufactured Home. They worked perfectly for our needs.

These units punch above their weight. I use them "off label" as it were, to provide a point of attachment for moving boulders, Some weighing a ton. I drill a hole using a carbide bit and jam these in, tighten them to about 40 ft lbs and using a winch, either drag or sometimes lift them. I would never use them in lifting above critical structures people or body parts but they are quite stout. For one ton and over boulders I might use two.

Perfect size fir what I needed for

Easy to use and they work. Recommended.

Didn't know if this would work at first had to drill a hole with a diamond but. The sunk this thing in with epoxy and tightened it up, never moved an inch. Used a 2000 pound engine hoist on it.

the anchors really do not work no one sells metric concrete bits, only standard and the only useful part was the loop that i used on a standard anchor after i welded it on to the nut to make it work

Seem well made, but the shank is 3/8 diameter, not 6mm. If you’re planning on making 1/4 inch hole and using these, you’re gonna be disappointed.

Got these anchors to mount my projector screen onto my concrete ceiling and install was super easy and quick!Got a few extras so may install a couple more on the balcony to hang some hammocks, when snug in their hole these hooks hold a lot of weight easily.
