A wedge anchor is a mechanical type expansion. Wedge anchors are to be installed in solid concrete only and is not designed to be used for other materials such as bricks and hollow blocks. Among the mechanical type expansion anchors, wedge anchors have the highest value in consistency and quality. A wedge anchor has four parts. Its parts include the threaded anchor body, the expansion clip, a nut, and a washer. Wedge anchors owe their holding values to its expansion against the base material. Upon inserting the hole to the concrete, expansion is created. Through turning the nut clockwise, the anchor body is pulled up to the nut. When using wedge anchors, it is critical to note the distance between wedge anchors and the distance from an unsupported edge of the concrete. “Generally, the spacing requirements used in several industries are that the anchors should be spaced a minimum of 10 anchor diameters away from each other and a minimum of 5 anchors from an unsupported edge of the concrete.”
