Steel Torx Flat Head Screws for Wood and Composite Wood

The thin head reduces surface damage and leaves a smooth, near-invisible finish on decking and trim. These screws are also known as trim head screws. With a deep six-lobe opening, their Torx drive handles more torque than slotted, Phillips, and hex drives. The flat head creates a discreet look in countersunk holes and deters snags.

Drill a pilot hole slightly smaller than the screw to prevent splitting. Length is measured from the top of the head.

Green Corrosion-Resistant-Coated Steel—The dark-green coating resists rust at the level of stainless steel. All of these screws have passed a 1,500-hour salt spray test.

Stainless Steel Square-Drive Flat Head Screws for Wood and Composite Wood

Fasten decking and fencing outdoors with screws that won't rust. They're often used with chemically treated wood, such as ACQ-treated (arsenic-free) lumber. Also known as deck screws, their trumpet shape spreads pressure to prevent splitting, while the flat head limits snags. The square drive handles more torque than slotted and Phillips 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.

316 Stainless Steel—Superior to 18-8 stainless steel, these screws won't degrade when exposed to harsh weather, salt water, and most chemicals.

Steel Square-Drive Flat Head Screws for Wood and Composite Wood

The thin head reduces surface damage and leaves a smooth, near-invisible finish on trim, drywall, and other surfaces. These screws have a square drive that handles more torque than slotted and Phillips drives. Their flat head sits flush so they won't snag.

Drill a pilot hole slightly smaller than the screw to prevent splitting. Length is measured from the top of the head.

Black Phosphate-Coated Steel—More corrosion resistant than black-oxide steel, these screws are suitable for environments with minimal moisture. They have a dark, matte coating to create a finished look.
