I found this set of five Type 304 Stainless steel drop-in anchors to be a good value.The anchors came in a small plastic storage case with no instructions or specifications.Typically, a 5/8-11 drop-in anchor would require a 7/8” diameter hole, however, these anchors fit well in a 3/4” hole, as they are a bit smaller in diameter than other 5/8 drop-in anchors I’ve used. (Typically, for drop-in anchors, the drill bit used should be the same diameter as the outer dimension of the drop-in anchor, as masonry drills are typically slightly oversized.)I’m using these with stainless steel bolts to achieve an anchor that will not rust over time. These appear to be high-quality anchors and have worked as expected. You will need a 5/8 setting tool.Installation is easy: drill a 3/4” hole 1-1/2” deep in the concrete, blow out the dust, I also use a bottle brush to clean the hole and blow it out again to get a clean, dust free hole. Then, drop the anchor into the hole, it should fit flush to the surface. Place the setting tool in the anchor and strike it with a hammer to get the initial set. When you tighten the bolt, the anchor will expand a bit more securing it in place.
