Abstract
A bolt anchor is comprised of a body and sleeve. The body is generally wedge shaped with a threaded bore along its axis and at least one stop near its smaller end. The sleeve has a round collar with leaves extending from the collar parallel to the axis of the collar and each other. The at least one stop maintains the assembly of the body and sleeve. Prongs on the sleeve prevent the retraction or turning of the bolt anchor when a bolt is installed in a hole using the bolt anchor. Reduced material thickness associated with the leaves on the sleeve produces hinges which allow the leaves to be more easily deformed outwardly to engage the sides of a hole. Inserting a bolt and bolt anchor assembly into the hole and then turning the bolt pulls the body into the sleeve and creates a wedging effect in the hole.
