Stainless Steel wedge anchors are available in many types of finishes and material grades. The four most common types of wedge anchors in general are: zinc plated low grade carbon steel, hot dipped galvanized, 304 stainless steel, and 316 stainless steel. For dry and mostly indoor applications, zinc plated carbon steel wedge anchors perform well. If, however, you are using the anchors on a high moisture outdoor project, hot dipped galvanized or 304 stainless steel wedge anchors are recommended. 316 stainless steel anchors are more commonly used in highly corrosive or acidic environments, as they perform very well against such extreme elements. A typical package of our anchors comes complete with nuts and washers.
