Most Common Types Of Concrete Anchors

Concrete anchors are essential for securing objects to concrete surfaces. They come in various types, each designed for specific applications and load capacities. Here are some of the most common types of concrete anchors:

1. Wedge Anchors: Wedge anchors are commonly used for heavy-duty applications. They consist of a threaded rod with a cone-shaped end and a sleeve that expands when the nut is tightened. They provide strong holding power in solid concrete.

2. Sleeve Anchors: Sleeve anchors are versatile and suitable for a wide range of applications. They consist of a sleeve, an expansion cone, and a threaded stud. As the nut is tightened, the sleeve expands to grip the concrete.

3. Drop-In Anchors: Drop-in anchors are used when a flush-mounted anchor is required. They consist of a threaded insert and a setting tool. They are installed by drilling a hole, placing the anchor inside, and then using the setting tool to expand the anchor.

4. Toggle Bolts: Toggle bolts are used for medium-duty applications. They consist of a spring-loaded toggle that opens inside the wall when the bolt is inserted and tightened. They are often used for hanging heavy objects on drywall with concrete behind it.

5. Concrete Screws: Concrete screws, also known as masonry screws or Tapcons, are self-tapping screws designed for use in concrete, brick, or block. They are easy to install and can be removed and reused.

6. Expansion Bolts: Expansion bolts, also known as shield anchors or heavy-duty anchors, consist of a bolt, a sleeve, and a cone. When the bolt is tightened, the cone expands the sleeve to provide a secure hold.

7. Hammer-Set Anchors: Hammer-set anchors are designed for quick and easy installation. They have a pre-installed nail and are hammered into a pre-drilled hole in the concrete. These anchors are suitable for light to medium-duty applications.

8. Concrete Screws with Plastic Anchors: These anchors combine a concrete screw with a plastic anchor. The plastic anchor provides additional support and prevents the screw from pulling out of the hole.

9. Chemical Anchors: Chemical anchors use epoxy or other adhesives to bond with the concrete, providing a very strong and reliable hold. They are often used for heavy-duty and critical applications.

10. Pin-Type Anchors: Pin-type anchors are used for lightweight applications and can be driven directly into the concrete without the need for pre-drilling. They are often used for attaching furring strips or electrical boxes to concrete walls.

The choice of concrete anchor depends on factors such as the load capacity required, the type of concrete, the installation method, and the specific application. It's essential to select the right anchor and follow the manufacturer's installation instructions for a secure and safe attachment.
