ABSTRACT:
An expansion anchor grip sleeve assembly comprising an anchor grip sleeve axially aligned with an expansion anchor shield. The anchor grip sleeve possesses grasping prongs or locking means which engage the expansion anchor shield. A bolt passes through the anchor grip sleeve and expansion anchor shield with the bolt having threads that engage threads in the expanding plug in the expansion anchor shield, such that when the bolt is tightened the grasping prongs or locking means of the anchor grip sleeve engage the expansion anchor shield to activate the expansion anchor shield. This results in the establishment of the expansion anchor grip sleeve assembly in one or more surfaces.
