Plastic anchors and screws are commonly used for securing objects to surfaces like drywall, plaster, and masonry. Plastic anchors expand inside the hole when a screw is inserted, creating a firm grip to prevent the screw from pulling out. They are lightweight, corrosion-resistant, and ideal for medium-duty applications like mounting shelves, picture frames, and fixtures. Screws used with plastic anchors are typically self-tapping and designed to hold securely within the anchor. These fasteners are widely used in household and commercial applications where strong and reliable support is needed.
