Quality Expansion Anchors

For use in medium duty to heavy duty applications, the expansion anchor is best when a bolt is subject to side pressure or vibration, or shear loads are present. Expansion anchors are placed into a hole, and using the threaded fastener, the anchor is expanded into place. Note: not all expansion anchors can be used in the same building materials. While some can be used in concrete, brick or block, others can only be used in concrete or stone.
