- Expansion anchors are used in soft masonry and in materials of questionable strength with machine screws or machine bolts that are exposed to vibration or side pressure. Made of zinc alloy, expansion anchors are rustproof. The screw or bolt can be removed from the anchor if necessary and replaced while maintaining holding power. Double expansion anchors have two ends that, when expanded, hold in place using the full length of the anchor body.
