    Square/Phillips

    Drive

    Fasten plywood and oriented strand board your way with these rust-resistant screws. They have a combination drive, so you can use Phillips drivers to tighten them or square drivers if you need more torque. The flat head sits flush to prevent snags, while serrated threads cut through wood fibers to minimize splitting. Often used in exterior panels, they won't degrade from moisture or chemically treated wood.
    Length is measured from under the head.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
