ABSTRACT:
An expandable collet body and anchor system incorporating a collet body anti-rotation feature and preferably collet body translation arresting means are disclosed. The collet body includes a first end, a first wall portion having at least two fingers, a second end including a head, a second wall portion, an annular protrusion and anti-rotation means where the anti-rotation means engages with an auxiliary structure defining a hole having an internal surface adapted to translationally accept the collet body and operatively function with the collet body anti-rotation means. The auxiliary may include a work piece to be optionally joined to another structure or a sleeve insert locatable in a hole defined by a work piece. Because the collet body is relatively free to translate within the auxiliary structure, a wide spectrum of work piece depths can be engaged with a single length collet body with the use of a stud to radially expand the fingers, thereby engaging a distal structure.
