When anchoring to masonry, this base material encompasses a wide range of materials and not all masonry fasteners will work in all types of masonry. As a result, there is a wide type and range of fasteners available for anchoring to masonry.
Types of Masonry
Masonry, as it relates to masonry fasteners, includes concrete, block, brick, grout-filled block and mortar joints. All of these materials are widely used in the construction of homes, buildings, and infrastructure. The type of masonry will determine the type of masonry anchor used for any specific application. Masonry anchors’ holding values are directly related to the quality of the base material that it is installed.
Types of Anchors
There are two types of masonry anchors: mechanical/expansion anchors and adhesive anchors. This article addresses the mechanical expansion type masonry anchor. Expansion anchors work by creating an outward force against the inside walls of the hole in the masonry material. The anchor creates an outward force when it mechanically changes its form as it is inserted into the hole and then expanded. This creates the outward force that produces the friction that provides the holding values. Each type of masonry anchor expands differently based on the masonry material for which it is designed.
Some applications require the anchor to protrude from the surface of the masonry while others require it to be set flush with the surface. Other applications need a head that sits flush with the surface of the item being attached. Another consideration is whether the working end of the masonry fasteners will be in solid base material, such as concrete, mortar, grout filled block or hollow block or brick.
Stud Type Anchors for Solid Masonry
Flush Type Anchors for Solid Masonry
Drop-In Anchor– designed specifically for use in solid concrete and should not be used in brick, block or any other non-solid base material. Drop-in anchors are set in the concrete utilizing a set tool which is specifically designed for the diameter of drop-in being set. Internal threads are national coarse threads and are about equal to half the length of the anchor.
Stud Type Anchors for Hollow and Solid Masonry
There are not any types of anchor for hollow masonry that will just leave a stud sticking out from the surface. All of these fasteners would be described as follows:
Headed Type Anchors for Hollow and Solid Masonry
Flush Type Anchors for Hollow and Solid Masonry
Each of the masonry anchors which have been described is linked to a page that will provide more in-depth information about the following topics:

As with any anchoring project, it is important to keep safety in mind and follow instructions carefully. Always remember to wear safety goggles, handle all tools with extra care and follow all technical specifications. This article is meant to serve only as a basic explanation of concrete fasteners. Always refer to manufacturer's instructions or consult a contracting expert during any anchoring project.
