Hillman .15 in. D X 1 in. L Plastic Round Head Ribbed Anchor 100 pk

The expandet anchor is designed for light duty fastening applications in concrete, block, brick or stone. Use them with sheet metal or wood screws for proper installation. The ribs on the anchor body prevent it from turning while tightening the screw. (Screws are not included.) We recommend this anchor for light duty static applications where holding power isn't a critical factor. *
