Galvanized Phillips drive deck screws are a great choice for your decking and other outdoor projects. The galvanized finish on these screws provides excellent corrosion protection. Designed with a flat head and Phillips drive, these screws have a more accessible bit type and are easy to use. While this screw is fantastic for pressure-treated woods, the finish may cause staining in cedar or redwood. These screws conform to ASTM B695, including Weather Maxx 3 distinction.
