These black coated hex lag screws provide adequate corrosion and rust protection, making them a great choice for outdoor DIY projects. Use this lag screw to attach objects to wood. These coated lag screws have coarse threads designed for pre-drilled holes to prevent splitting or snapping. Minimal clearance is required above the fastener. The screws have a hexagonal drive for simple installation and controlled traction with a socket or wrench. Use in a pre-drilled hole, see product package for pre-drilling instructions.
