5/16" X 4-3/16" Expansion Concrete Wall Anchors Eyebolt Screw, Heavy Duty 304 Stainless Steel Shoulder Lag Eyebolts for Concrete Wall, 5 Pack

I bought these anchors not for a wall but for my carport. I just had it cemented recently and needed a couple anchors in the ground to hold and be able to clip in a privacy tarp. This worked perfectly. I drilled a deep enough hole in the cement and tapped this in and then turned the eye hook to expand the anchor. It is solid!, stays in place. Now I'm able to clip in the tarp with carbiners and I can remove the eyehook so I don't trip over it when I'm not using it. It's solid and a good deal and a win win for me.

Good quality. Size is accurate. Will buy again.

First off the hole needed to put these anchors in should be 1/2 inch in diameter and then prior to hammering it in put some anchoring adhesive in the hole then the anchor and be careful when hammering it in the shaft will bend. Then tighten it down and when the adhesive dries it will not move and stay for good.

Great expandable concrete eye bolts. Wonderful basement connectors for my Crossover Symmetry bands.

Good for many uses, but you have to get the correct mason bit size otherwise it’s too loose and the first time until I ordered a mason bit 1/64 it works like a charm. The first time was for my RV parking gate to stay open while moving my vehicles. It was kinda loose not tight so Mr Gizmo (Me) used JB Weld my favorite weld for lots of breakage! My little Glass bubbler fell And the top broke off,JB Weld did it and many other projects. I used it the second time with the correct bit that was very HARD to find in a mason bit. Worked good in my patio shade for “Bungee” wind support and my patio shades are down most of the year.

We used these to hold down our carport with heavy duty ratchet straps during hurricane Milton. Had to rent a concrete drill, but worth every penny for these, the straps, and drill!

Used these to secure Christmas nutcracker on front porch along with cables and locks.

Worked really well and easily installed
