An expansion shield is a type of anchor used to secure objects to materials like concrete, brick, or hollow walls. It works by expanding when a screw or bolt is inserted and tightened, creating a strong grip within the material. This makes it ideal for securing heavy items in construction and masonry work. The expansion shield is particularly effective in softer materials, providing a reliable and sturdy hold.
