Abstract
A drop-in anchor system includes a drop-in anchor having a tubular sleeve with a first end and an expandable second end. The sleeve tapers in inner diameter from the first end to the second end at a sleeve taper angle. The drop-in anchor includes a plug insertable in the sleeve such that when the plug is driven into an installed position in the sleeve the second end expands. The plug tapers at a plug taper angle from a head end to a tip end and a difference between the sleeve taper angle and the plug taper angle is about one degree or more. The system includes an installation tool configured to form a hole in a workpiece into which the drop-in anchor is insertable and to drive the plug into the installed position in the sleeve.
