Abstract:
1. An apparatus for fastening objects, comprising: an elongated body having a distal end and a proximal end; an external anchor section on a distal portion of the body for anchoring the distal portion of the body to an object; a spring section in the body at a location between the anchor section and the proximal end, the spring section allowing the body to elongate from an initial length when being fastened in the object, but urging the body toward the initial length; a proximal drive surface at a location proximal of the spring section for imparting torque to the body proximal of the spring section; a distal drive surface at a location distal of the spring section for imparting torque to the body distal of the spring section at the same time torque is imparted by the proximal drive surface; wherein the body is hollow, and the apparatus further comprises: a stabilizing pin that is inserted into the body after the body is in full engagement with the object, the stabilizing pin extending through the spring section and being rotatable relative to the spring section during insertion of the stabilizing pin into the body.
