Lag-Master is a structural corrosion resistant heavy duty wood screw recognized by ICC in ESR 3531 for applications such as, landscape timbers, fences, decks, headers, stair stringers, attaching rafter or trusses to the top plate and more. Lag-Master fasteners may be used in place of ¼” and 3/8" lag screws and is code approved for use in treated lumber. Its friction reducing exterior coating, type 17 point and aggressive 10 TPI threads zip right in to the densest woods.
Lag-Master timber fasteners are mechanically galvanized coated against corrosion B695 Class 55. Grabber’s galvanized coating is ACQ compliant, and is may be used in place of Hot Dipped Galvanized products as described ASTM A153.
