    Steel Torx Flanged Rounded Head Wood Screws

    Image of Product. Front orientation. Wood Screws. Steel Torx Flanged Rounded Head Wood Screws.
    Prevent splitting and other damage from high torque when fastening surfaces such as cabinets, trim, and molding. The flange on these screws spreads pressure evenly across a wide area. All have a domed head. The Torx drive handles torque better than slotted, Phillips, and hex drives. Also known as star drives.
    Drill a pilot hole slightly smaller than the screw to prevent splitting. Length is measured from under the flange.
    Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

    Steel Torx Flat Head Wood Screws

    Turn up the torque without slipping and stripping drives. Also known as star drives, these Torx screws withstand more torque than screws with a slotted, Phillips, square, or hex drive. The flat head sits flush, so you won't need to worry about snags.
    Drill a pilot hole slightly smaller than the screw to prevent splitting. Length is measured from the top of the head.

    Distortion-Free Screws for Composite Wood

    Image of Product. Front orientation. Wood Screws. Distortion-Free Screws for Composite Wood.
    Reverse threads pull stray material inward instead of letting it bulge out to the surface. The flat underside of the pancake head creates a strong hold without the need for a countersunk hole. The Torx drive handles more torque than slotted, Phillips, and hex drives.
    The screw drill tip acts as a built-in pilot, though pilot holes are still recommended near edges to avoid splitting. Length is measured from the top of 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.
