Fastenmaster 2-1/2 in. GuardDog® Exterior Wood Screw, 75-Pack exceptional performance with its TORX® ttap® Drive System, ensuring stick-fit and wobble- installations. These versatile exterior wood screws are for a wide range of outdoor projects, including pressure-treated decking, railings, stair stringers, deck frame blocking, dimensional headers, pergolas, and more. Designed for durability, they are fully tested and to work effectively with pressure-treated lumber, cedar, redwood, and chemically treated wood. For a clean and polished finish, the screws feature nibs under the head and a UV-resistant coating that prevents fading and chalking. Installation is quick and easy thanks to aggressive threads that provide strong holding power and a sharp, type 17 point. A standard T25 TORX® driver bit can also be used if needed. For optimal results, install two fasteners per deck-to-joist connection, and predrilling is only when fastening near the end of a board or when working with hardwoods. Model Number: FMGD212-75
