Abstract
A drive pin assembly for use with a power tool to install a drop-in anchor includes a drive pin body, and a drive pin disposed within the drive pin body and configured to be inserted into the drop-in anchor. The drive pin is moveable relative to the drive pin body between a retracted position and an extended position. The drive pin assembly also includes a threaded die supported by the drive pin body and configured to be inserted into the drop-in anchor with the drive pin. The threaded die is movable radially outward by the drive pin as the drive pin moves from the retracted position toward the extended position.
