1. A method for implanting an anchor in bone, comprising:
rotating an inner shaft of an inserter tool relative to an outer shaft of the inserter tool to rotatably drive a threaded expander screw distally into a threaded inner lumen of a sheath coupled to the outer shaft and disposed within a bone hole, the expander screw causing the sheath to expand radially outward to engage bone, and the inner shaft having a vertical stop surface formed on a distal end thereof that engages a corresponding vertical stop surface formed on a proximal end of the expander screw to limit distal advancement of a distal drive tip of the inner shaft into a drive recess of the expander screw to a predetermined insertion depth such that over-insertion of the distal drive tip into the expander screw is prevented, each of the vertical stop surfaces having a height that is less than a thread pitch of the expander screw.
