Structural Lag Screws 5/16" X 3-1/2", 40 Pieces

Structural lag screws are heavy-duty fasteners designed for framing, decking, and other demanding construction and woodworking projects. These 5/16" x 3-1/2" screws feature a corrosion-resistant coating and are engineered for use with treated lumber.
