Zinc Plated Steel Toggle Bolt Anchor Spring Toggle Bolt
Wedge anchors, also known as red head bolts, expansion bolts and expansion anchors, secure themselves using a mechanical wedging effect at the end of the fastener. There are three basic styles of wedge anchors: fully threaded, partial threaded and the full-bodied wedge anchor.[4] As shown in the figure, tightening the bolt results in a wedge being driven up against a sleeve. This jams the end of the bolt, and provides the strength. Many different manufacturers provide a variation on this theme, usually depending on the condition of the concrete, and the type of load. If a mechanical anchor fails, it is usually in the form of pulling out a wedge of concrete, and for this reason, proper design looks at the depth of embedment and ensures that the bolts are not spaced too closely.
A specialized form of the anchor bolt is the rock bolt, used in rock excavations. In many parts of the world seismic anchors are another specialized subject.
