    Stainless Steel Phillips Rounded Head Screws for Plywood and Oriented Strand Board

    Image of Product. Front orientation. Wood Screws. Stainless Steel Phillips Rounded Head Screws for Plywood and Oriented Strand Board.
    Serrated threads on these rust-resistant screws cut through wood fibers to minimize splitting. When exposed to moisture and chemically treated wood, such as ACQ-treated (arsenic-free) lumber, these screws won't rust or corrode. All have a domed head, and the Phillips drive handles enough torque to drive into most kinds of wood without slipping.
    Length is measured from under the head.
    316 Stainless Steel—Superior to 18-8 stainless steel, these screws won't degrade when exposed to harsh weather, salt water, and most chemicals.

    Stainless Steel Phillips Flat Head Screws for Plywood and Oriented Strand Board

    Image of Product. Front orientation. Wood Screws. Stainless Steel Phillips Flat Head Screws for Plywood and Oriented Strand Board.
    Serrated threads on these rust-resistant screws cut through wood fibers to minimize splitting. They're often used with plywood and oriented strand board (OSB) for exterior panels. They also won't corrode from moisture or chemically treated wood. The flat head sits flush, so you won't need to worry about snags. The Phillips drive handles enough torque to drive into most kinds of wood without slipping.
