Abstract

An anchor member is formed of an axially extending core member enclosed from one end toward the other by an electrically non-conductive plastics material jacket. The anchor member can be secured in a borehole in a receiving material by a hardenable mass. The jacket at the one or leading end of the core member has a tip located on an extension of the core member axis, so that the tip abuts the center of the base of the borehole. With the centering action afforded by the tip, damage to the jacket is prevented as the anchor member is inserted into the borehole.
