Safety goggles
Nose mask and other essential safety gear

Installing masonry anchors can be done with a little knowledge and study about how to do it. The anchors are of four types i.e. concrete screws, one-piece expansion anchors, two-step expansion anchors and hammer anchors. Here is how you install masonry anchors.

Step 1 - Choose the Type of Anchor

Choosing the right type of anchors is the first and most important step in anchor installation. The anchors are chosen with respect to the weights they carry and the nature of the concrete, into which the anchor is drilled. Some anchors are used to fix glass or wooden sheets or blocks to the concrete. Concrete screws are the easiest to install and can be used to fix household items. Hammer anchors are efficient for light duty loads and expansion anchors are used for heavy-duty loads

Step 2 - Drill a Hole into the Material

Drill a hole into the material, which has to be mounted on the concrete. This can be a piece of wood, or household equipment or bookcase or a shelf. The hole drilled needs to be large enough for the screw body to pass but not larger than the screw head. If you are installing hammer anchors, the hole should be enough for the flange body to pass, but not the flange head. The drilling should be precise and straight. Care should be taken that the hole isn't too big. While drilling and installing, make sure you wear proper safety gear.

Step 3 - Place the Anchor onto the Wall

Now take the material to be mounted to the wall. Using a pencil or a marker, mark the spots where the holes have to be drilled. Once the marking is done, keep the material aside and drill a hole in the wall. This hole should not be longer than the anchor's body. Depending on the anchor type, either drill or screw or hammer the anchor into the wall leaving little space for placing the material. Hammer anchors use hammers instead of drills or screwdrivers and are efficient for light duty loads and cannot be used for overhead installations.

Step 4 - Fix the Anchor to the Wall

Once the anchor is fixed to the wall, hang the material to the anchor. Now, using the screw heads fix the material properly to the anchor. Use a wrench or hand to ensure that the anchor is tightly fixed in its place. If you are using two-step expansion anchors there is a slight change in fixing the anchor to the wall. Here a plate or disk is first fixed on the wall. On this is done, the material is screwed on this anchor, using a special set of tools. 

The anchors get fixed to the wall tightly so that they don't loose the grip. So once fixed, if an attempt is made to remove the anchor, it will come out with the concrete itself.
