Fasteners are called anchor fasteners in the building trade. They connect something to a base material such as concrete, brick or plasterboard. In most cases, anchor fasteners are installed by first drilling a hole in the base material. Then the anchor is inserted into the hole. The distance to which the anchor penetrates into the base material is called the embedment depth. Anchors are required to resist forces in two directions. Pullout forces are those that act in the direction of the axis of the fastener. Shear forces are those forces that act at right angles to the axis of the fastener.
