Stainless Steel Phillips Flat Head Drilling Screws for Joining Wood to Sheet Metal

With Cutting Wings

These rust-resistant screws join wood to sheet metal by drilling, tapping, and fastening in one go. Their self-drilling tip clears the way while their threads tap into the material. Made of stainless steel, they also won't degrade from chemically treated wood, such as ACQ-treated (arsenic-free) lumber. 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.

Length is measured from the top of the head.

Galvanic-Barrier-Coated 18-8 Stainless Steel—A protective layer stops corrosion from metal-to-metal contact. A good choice for outdoor and wet environments, these screws also won't rust.

Cutting-Winged Body—These wings create a tight hold by preventing screw threads from engaging until they reach the sheet metal. Then, the wings snap off so the screw can switch from drilling through wood to fastening into metal.
