DécoScrews are a screw and anchor in one.
DecoScrews install with a screwdriver and replaces the complicated hanging systems that need a drill, anchor and fastener.
Strong and easy to install
DecoScrews are designed to securely hang heavy wall décor in standard drywall without puncturing wiring or plumbing. This screw and anchor in one is designed with a cone shaped shank that can hold items up to 30 lbs on a single screw. DecoScrews are easy to install with either a flat or Phillips screwdriver. They are perfect for hanging pictures, clocks, mirrors and other wall décor in drywall, in record time. Please do not use these screws to install floating shelves.
