Manufactured to be extremely sturdy, lag screws are some of the toughest fasteners. This stainless steel hex lag screw offers a higher level of corrosion resistance and is great for any outdoor project. Use this lag screw to attach objects to wood and concrete. Common applications include retaining walls, deck frames and outdoor play equipment. When used in conjunction with a lag shield, this screw can also be used in masonry applications. This screw has coarse threads with a hexagonal drive. Its stainless steel finish provides anti-corrosive properties and makes it slightly stronger than regular (un-hardened) steel bolts. Use this screw in a pre-drilled hole.
