Review on 🔩 MKT Conset Masonry Anchor Fasteners: Optimal Diameter for Screw Connection by Jarrett Love

I bought a box of these about four months ago and they have worked great. I bought a second box and failed seven out of eight. All broke entering the hole I drilled. I stopped using them and bought a box of Home Depot Tapcons since I just didn't have time to drill holes and remove screw heads. I would give them back to Revane but it's not worth the time and effort. I will throw them away and never buy them again. I suggest others find another source as well.
