Additional Information

The category of fasteners labeled as "concrete anchors" describes fasteners that are used to fasten items to concrete, brick, and block. All the fasteners sold by Concrete Fasteners are designed for placement in the concrete after it has hardened. None of the fasteners are the type that can be cast in place.

The anchors sold on this site are divided into these four categories:

- Concrete Anchors, which are all the masonry fasteners that carry the CONFAST® Logo

- Tapcon® brand masonry screws

- Bits that are designed for drilling holes in the concrete for concrete anchors

- American Made, which are all the concrete anchors manufactured in the United States

The following list contains all the anchors that are stocked and sold by Concrete Fasteners Each item is a link to the specific product page that will provide detailed information. Each product page offers specific anchor information, product specifications, applications videos, installation instructions with the corresponding video, and application photos.

On the left side of this page is a user-friendly product filter that will help to narrow choices based on different attributes. Each of the filters allows for fast and easy selection to give the best results for the requirements listed. When in need of a specific diameter, length, material, environment or type, simply click on the arrow and make a choice. Filtering by categories or by the manufacturer is also an option.

Bits

The bits for drilling holes in concrete to set concrete anchors must be drilled using a hammer drill that is set in the hammer and rotation mode using a carbide tipped bit. The carbide tipped bits are manufactured to allow for maximum dust removal allowing for fast drilling speeds. The process of drilling into concrete is to first pulverize the material via the hammering motion and then remove the dust that is created via the flute. The drilling speed is directly related how fast the dust is removed from the hole and the force delivered through the hammering motion.

American Made

The line of American made concrete anchors is domestically manufactured. Verification can be provided with each order if requested. The wedge anchor comes with nuts and washers; however, the nuts and washers are not American made.

Below is a listing of our complete line of American made concrete anchors.
