Confast Wedge Anchors: Key Features and Information

Confast wedge anchors are mechanical concrete anchors designed for use in solid concrete. Installers most commonly use these anchors in construction and industrial applications to secure objects to concrete surfaces. Here are some key features and information about Confast wedge anchors.

Design and Construction

Confast wedge anchors consist of a threaded stud, a metal expansion clip, a nut, and a washer. The wedge anchor is inserted into a pre-drilled hole in the concrete, and as the nut is tightened, the metal clip expands to securely anchor the stud in place.


Manufacturers most commonly make these anchors of materials such as zinc-plated carbon steel, or galvanized steel. When there is a need for corrosion resistance or durability, they use stainless steel.


Installation involves drilling a hole into the concrete of a diameter matching the anchor size. You then insert the anchor into the hole. Once complete, tighten the nut to expand the clip, creating a tight connection.


Confast wedge anchors are suitable for a variety of applications, including securing structural elements, equipment, machinery, and other fixtures to concrete surfaces.

Sizes and Capacities

These anchors come in various sizes to accommodate different load capacities. Diameters range from 1/4″ to 1-1/4″. The anchor lengths, which depend on the diameter, are from 1-3/4″ to 12″

It’s important to choose the appropriate size and type based on the specific application and load requirements.


One of the advantages of Confast’s wedge anchors is their ability to provide a secure and reliable connection in solid concrete. They are relatively easy to install and offer good load-carrying capacity.
