Claim:
1. An anchor for embedding into a borehole having an undercut region, the anchor comprising a shaft; a head adjacent to one end of the shaft and extending laterally from the shaft; a sleeve axially surrounding the shaft; an adjustable clamp juxtaposed to the sleeve for moving the sleeve along the longitudinal axis of the shaft; and a deformable plate positioned on the shaft between the head and the sleeve, wherein the deformable plate is capable of movement between a first position wherein the plate is substantially confined to an area within a perimeter of the head and a second position wherein the plate is substantially uniplanar and perpendicular to the shaft and, with a perimeter of the plate extending at least partially beyond a circumference of the borehole and into the undercut region, and wherein movement of the sleeve along the shaft towards the head moves the deformable plate between the first and second positions.
