ABSTRACT:
A screw type anchor device for securement into masonry structures. A sharp crested helical thread, preferably with tapering crest diameter, is formed along the shank and helical protuberances forming guide means are spaced along the shank between adjacent convolutions of the helical thread. Notches are formed on the crests of the helical thread along the length of the shank to facilitate embedment of the crests in the walls of a performed bore in the masonry structure.
