The GRK RT Composite Screw is specifically designed for attaching composite decking, trim, and cellular PVC materials with a professional, flush finish. Its reverse threading under the head prevents mushrooming, allowing the screw to sink neatly below the surface for a smooth, even appearance. Featuring a trim head and Zip-Tip point, these screws enable one-step, no-pre-drilling installation, saving time while ensuring precision. W-Cut threads reduce installation torque for fast, effortless driving, and the star drive design prevents stripping for improved productivity on every project. Coated with Climatek corrosion-resistant finish, the RT Composite Screws are suitable for interior and exterior applications, including areas with intermittent moisture, and are code-approved for use in treated lumber. Backed by a limited lifetime warranty, they deliver durable, professional-quality results for composite and PVC projects.
