Sleeve anchors - one kind for brick and block, another for concrete - come in different lengths as well. When drilling the hole for a 1/2-inch sleeve anchor you actually drill a 1/2-inch hole. The sleeve is slipped into the hole and, when the bolt is inserted, the sleeve expands and grips.
How to use: First, drill the proper size pilot hole (3/8-in., 1/2-in., etc.) through the wood or metal and into the concrete. Slip the sleeve anchor into the hole. Hold the object you're fastening firmly against the wall because the anchor will draw it only slightly tighter as you tighten the screw or nut.he best way to drill a hole into concrete, concrete block, mortar and brick is to use a hammer drill. A standard drill will do OK in soft brick and mortar, but it'll just frustrate you and burn out bits in harder materials. DON'T BURN OUT YOUR FAVORITE 3/8-IN. DRILL.
