1. Product Description
Wedge anchors, also known as 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. 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.
All wedge anchors are hammered into the hole in the concrete with a hammer. Once the threads of the wedge anchor are below either the surface of the concrete or the surface of the material being fastened then the wedge anchor is ready to be set into the concrete. The nut is first finger tightened and then a wrench is used to turn the nut clockwise until the correct torque is applied. The correct torque is dependent on the diameter of wedge anchor being used. Once the wedge anchor is torqued to the proper torque value for the diameter of wedge anchor being used then the wedge anchor is safely set.

The wedge anchor has a clip that wedges between the body of the wedge anchor and the wall of the hole in the concrete. The wedge anchor is set after its clip has been set using the correct torque values for the diameter of wedge anchor being used.
The minimum length of wedge anchor to be used for any type of application is determined by adding the thickness of the material being fastened to the minimum embedment for the diameter of wedge anchor being used, plus adding space for the nut and washer. The space for the nut and washer is usually equal to the size of the diameter of the wedge anchor being installed. For example, if a 5/8” wedge anchor is being installed then the space for the nut and washer would equal 5/8”.
