EspañaA double expansion anchor is used to anchor a masonry hinge with a material type of questionable strength or quality. In the world of masonry anchors, most rely on deforming the part near the bottom of the anchor in the hole to prevent the anchor from loosening.
Double expansion anchors are different from other masonry anchors. It is not that the bottom of the anchor expands sharply to create a strong grip, but the size of the entire anchor expands only slightly to distribute the pressure over the entire surface area of the anchor.
