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.

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
 |
Reverse threads pull stray material inward when fastening composite wood 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.
