Which type of fastener is known for its use in masonry applications?

The correct choice for fasteners commonly used in masonry applications is expansion anchors. These fasteners are specifically designed to provide a secure hold in solid materials like brick, concrete, or stone. When an expansion anchor is inserted into a pre-drilled hole in masonry, it expands upon tightening, creating a strong grip against the surrounding material, which is essential for ensuring stability and safety in applications involving heavy loads.

The unique design and function of expansion anchors make them suitable for a variety of masonry tasks, such as securing fixtures, shelving, and other types of installations where robust anchoring is crucial. Other fasteners, like wood screws and sheet metal screws, are intended for different materials and applications, and while plastic anchors might also be used in masonry to some extent, they typically do not provide the same level of strength and durability as expansion anchors in demanding environments.
