Drywall anchors are used to secure items to drywall where screws alone would not provide adequate hold. They expand or grip the drywall, providing additional support for hanging heavy items. Drywall anchors are commonly used for mounting shelves, installing towel racks and bathroom accessories, hanging picture frames and mirrors, and securing curtain rods and blinds, ensuring that these items stay securely in place.
