Mortar is a cement-like material that is used to hold bricks and other types of building blocks together in a variety of construction projects. It is not uncommon to want to mount or hang objects from a brick wall. The easiest way is to insert the screw into the mortar instead of into the brick. Although this material may seem impossible to insert screws into, it can be done with the proper tools.
Concrete screws are readily available in any hardware or home improvement store. They are best used for cosmetic projects such as hanging shelves or signs, since they can be easily removed and replaced if necessary. Concrete screws look and function just like any other screw but are made out of a hardened steel that is ideal for masonry.
Hammer anchors are best used for mounting lightweight objects to masonry and mortar. They are more difficult to remove but can be pulled out with some effort. These anchors are similar to other types of wall anchors in that they are comprised of a screw and a sleeve that fits over the shank of the screw. However, hammer anchors are made out of materials suited for use in mortar.
One-Piece Expansion Anchors
There are two types of one-piece expansion anchors, sleeve anchors and wedge anchors. Both of these types of anchors are made out of steel and are therefore much stronger than plastic anchors. This strength makes them suited for heavier construction projects. These anchors work the same way as well. As the screw is tightened, the sleeve or the wedge attached to the shank of the screw expands to create a tight fit inside the mortar. Neither of these anchors can be removed after installation.
Two-Step Expansion Anchors
These types consist of an anchor that can be used with a traditional screw, usually made out of nylon or plastic and expand when the screw is tightened inside of them. This expansion creates a hold that keeps the screw and anchor in place.
