Locate where you want to drill. With the concrete bit and drill, drill a hole in the patio 2 1/2 inches down. Place the drop-in anchor in the hole and tap it until the top is flush with the patio.
Place the screwdriver into the anchor and firmly strike the top of the handle five times with the hammer. This pushes the pin inside the anchor down and pushes out the sides so that it cannot come out of the stone.
Drill a hole in the object that you want to anchor to the patio. Place the hole over the anchor and place a washer over the hole. Insert the bolt through the washer and hole and screw it into the anchor until you cannot screw it anymore. Use the crescent wrench to tighten the bolt.
