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.
Sleeve Anchor â¢ Has a steel sleeve on the shank, split at the bottom so it can expand.â¢ The bolt has a cone-shaped plug at the base and a nut at the top.â¢ When the user places the anchor in the hole and tightens the nut, it draws the bolt upward, pulling the plug into the sleeve and expanding it against the hole.
