Review on CONFAST Hot Dipped Galvanized Wedge Anchor Fasteners and Anchors by Warren Hess

Used to anchor iron gate posts into concrete. Tip: Do not use an impact wrench on anchors. Use a wrench instead. Impact wrenches can easily over-tighten anchors. This applies not only to these anchors, but to all anchors without exception. These were strong, good threads. I didn't have to use epoxy or anything like that. Just drill the appropriate hole and insert them. It's better if you place a washer + nut and then slide it through the hole/base of what you are attaching. then just pound them onto the nut.
