Lag Shields
Relatively inexpensive and widely available, these internally threaded lead or alloy anchors are designed to work with lag screws in concrete and a variety of other masonry materials. Long lengths are used in softer base materials; short versions can be used in harder materials to cut drilling time. Lag shields are stronger than plastic anchors, but not as strong as expansion anchors like the wedge, sleeve or drop-in. A lag shield should fit snugly into its pilot hole, which is larger than the diameter of the fastener you intend to use. For example, an anchor for a 3/8-in. lag screw fits in a 5/8-in.-dia. hole. The hole should be deep enough so the lag screw doesn't bottom out.
