Plastic bolt sleeves, also known as plastic expansion anchors, are fasteners designed for light-duty applications in concrete, brick, or block. These anchors consist of a plastic sleeve and a metal screw. When the screw is driven into the sleeve, it expands to create a secure hold within the base material. Plastic bolt sleeves are often used for attaching fixtures, electrical boxes, and lightweight equipment to masonry surfaces. They offer a cost-effective and easy-to-install solution for non-structural fastening needs.
