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 anchorAs 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.
