Hello friends. In this video I want to show you how to install these gadgets. These are drop in anchors or expanding metal anchors. After we place them in a hole, we strike them with a special tool to expand the anchors. Then we screw in a thread, which can be used to hang different things. So, I already have a few installed, there you can see the holes, there, there and there. There I have an anchor in its hole. There I have another one and now I’m going to explain how this is done. We drill a hole in the concrete, first with a thin drill bit as a guide for the wider bit. First, we place the hammering end, where we have to drill, verifying the drill bit is perfectly plumbed, and we try to hold this position while we verify it’s set at right angles on the other plane. This should be the right position for the thinner drill bit,
the bit that will be used as a guide. Now with the full size drill bit we do the same thing. We place the end in the hole, we verify it’s perfectly plumbed on one side, and that it’s set at right angles on the other plane. The hole must be 1 1/2 inches deep. To fix the anchors we first insert them fully and using a hammer or better, with a piece of wood, we softly beat it in. If necessary, we can hit it a bit harder, but if we overdo it we might mar the thread and then we’ll make it useless and difficult to replace. However, if it gets stubborn despite
it should fit perfectly well inside that hole size, then we must use another tool. We cut a small threaded rod of the same kind, we screw it in till it touches the expanding pin and now we can hit it with the sledgehammer at will. There we are. Now we take off this part, we unscrew the small rod and we are ready to insert the setting tool. The setting tool pushes a pin that opens the anchors, making the drop in anchor irremovable. So, we insert the setting tool, and give it a few blows to push it in and that should be enough. We can also make our own setting tool using an old intake valve, grinding the stem to the inner diameter of the drop in anchor. This is a free option if we have an old valve around
or a car mechanic as a friend. Then we screw in the threaded rod. First with our hand
and then with a tool. After screwing the threaded support rod into the drop in anchor we screw on two nuts at the other end of the rod. We screw them on with our fingers and then with two wrenches turning counteractively, we fix them in place, giving us a handle that turns the threaded rod into the drop in anchor creating a blockage that won’t let the anchor’s legs, loose hold inside the hole. Then we let the nuts free turning them in the opposite directions. There. We free the nuts leaving the threaded rod inserted. Now we can hang a steel form
or any other object from the ceiling. It’s hanging firmly from the ceiling thanks to the drop in anchor. Now, let’s measure the angles to verify if they are set right. In this case we have an angle that is near perfect, a very small deviation from the vertical. In this other plane, we have a small deviation, but less than a 1/4 inch. Near perfect. That’s it.
