SPAX Stainless Steel Premium Exterior Wood Screws excel in decking, railing, fencing, and more. Their 304 stainless steel construction resists staining near fresh water and meets code for ground contact, pressure-treated, and fire-retardant lumber. A flat head design delivers a flush finish, while the patented tip and serrations drive quickly without pre-drilling. The included star drive bit ensures reliable, slip-free fastening for every outdoor wood project.
