GuardDog Exterior Wood Screws

FastenMaster’s enhanced GuardDog exterior wood screw has a Torx ttap drive system, a type-17 auger point for quick cutting into the wood surface, and cutting nibs under the head. The screws can be used for pressure-treated decks, railings, and stair stringers and are approved for use with treatments such as ACQ and CA-B and in acidic woods such as cedar and redwood. The fasteners are available in lengths ranging from 1 5/8 inches to 3 1/2 inches and in quantities up to 1,750-piece buckets. A 75-piece box retails for around $10. fastenmaster.com
