Abstract
A drop-in anchor includes a tubular sleeve having a first end and an expandable second end, the sleeve having one or more raised surfaces at the first end. A plug is insertable in the sleeve such that when the plug is driven into an installed position in the sleeve the second end expands and an installation tool interacts with the one or more raised surfaces to provide a visual indication of engagement of the drop-in anchor to a workpiece.
