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.
It is very typical for square plates to be used in place of F436 washers on the projecting threaded end of the anchor bolt, but perhaps even more common is to weld or fix in place a square plate at the bottom of the anchor bolt for pull out resistance.
