Engineered for optimum performance in multiple materials, Power Pro 1 screws are the 1 screw you'll ever need. Developed to outperform and replace standard wood, sheet metal and concrete/masonry screws, the 1 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. The bronze epoxy coating is recommended for exterior projects and treated lumber (Not recommended for marine applications or projects within 5 ml of coastal waters). The flat head design and star drive provide easy and clean countersinking into wood. 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.
