The function of the anchor is to assemble two pieces of different materials permanently to make it into a single unit. The threaded portion of the rod’s length is penetrated deep inside the material and is protected from the damage by the round design at its extreme end. They are subjected to hold the loads with the great strength and are used in the diverse applications for its super grip. A pilot hole is drilled just before the time of the installation to guide the way of the fastener. Screw the anchor into the hole and assemble the remaining pieces together including the nut and the washer.
