Engineered for optimum performance in multiple materials, Power Pro ONE screws are the ONE screw you'll ever need. Developed to outperform and replace standard wood, sheet metal, and concrete/masonry screws, the One Screw program simplifies your tool box by using a single, innovative, engineered screw design to satisfy projects that fasten into wood, metal, concrete, drywall, and plastic. This yellow zinc plated screw is ideal for interior wood applications; it is not recommended for exterior projects or treated lumber. Common applications include cabinet installation, low profile applications, and where a wide bearing surface is required. Its wafer head design and star drive provide fast driving and a clean finished look. Manufactured with spiral flutes, serrated hi-lo threads, and a 3-sided pyramid point, no pre-drilling is required in wood, drywall, plastic, or metal up to 20 gauge thick. Concrete and masonry applications require a pre-drilled a hole, see product packaging for pre-drilling instructions. Each package includes a free durable Pro-Stik Star Driver Bit. All ONE Screw products offer a limited lifetime warranty.
