Concrete wedge anchors are an excellent value at a low margin cost and are readily available from Tanner.

Installation is achieved in a few steps and once installed there is little room for error. All DEWALT wedge anchors have an ACI (American Concrete Institute) category ranking of 1.

The DEWALT concrete wedge anchor has been recognized by the ACI in cracked and uncracked concrete including seismic and wind loading.

Each DEWALT Power-Stud concrete wedge anchor has different applications and uses based on anchor material composition (body, expansion clip, nut, washer).

How do Wedge Expansion Anchors work?
The anchor body consists of a medium carbon steel threaded rod on one end and a tapered mandrel at the other end. The tapered mandrel is surrounded by a three-section expansion clip that moves freely around the mandrel. The movement of the expansion clip is restrained by the mandrel taper and by a collar. The anchors are installed in a pre-drilled hole with a hammer. Tighten the anchor with a torque wrench by applying the required installation torque. When torque is applied to the nut on the threaded end of the anchor body, the mandrel at the opposing end of the anchor is drawn into the expansion clip, pushing it outward into the sides of the predrilled hole in the base material.
