Wedge anchors also known as concrete wedge anchors, are made of zinc plated carbon steel, hot-dipped galvanized carbon steel, 303 stainless steel, and 316 stainless steel. This anchor is one kind of mechanical expansion anchor that can be divided to four parts: the threaded anchor body, the expansion clip, a nut, and a washer.
