An anchor for masonry. The anchor is relatively smooth walled and is forcibly driven into a hole formed in masonry or other suitable material for purposes of attaching fixtures. When driven into the hole, a shaped portion of the anchor is deformed in such a manner as to facilitate a 360 degree or greater bearing surface with the holes of wall. The walls of the hole impose forces onto the shank along this bearing surface which tend to deform shank into alignment with the hole by primarily elastic deformation so that the resulting frictional forces between the shank and the wall resist dislodgment from the hole.
