Wedge Anchors

Wedge anchors are used for attaching fixtures to a solid such as concrete. The installed end of the anchor features a conical segment with a metal clip around it. Upon setting the anchor, the cone pulls up through the clip and pushes the clip against the sides of the hole. This gives the anchor its holding power within the hole. Anchor diameter will be equal to the hole size. Expansion of the wedge anchor creates large point bearing stresses within the hole; therefore, this anchor requires a solid base material to develop its full capacity. For this reason, brick and partially filled mortar joints in brick walls or paving may be unsuitable for wedge anchor usage.
