Steel Phillips Flat Head Screws for Wood
These screws are beveled under the head for use in countersunk holes. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Length is measured from the top of the head.
Zinc-plated steel screws resist corrosion in wet environments.

Brass Phillips Flat Head Screws for Wood
Brass screws are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. All are beveled under the head for use in countersunk holes. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Length is measured from the top of the head.

18-8 Stainless Steel Flat Head Screws for Plywood and Oriented Strand Board
18-8 stainless steel screws have good chemical resistance and are a good choice for ACQ-treated (arsenic-free) lumber. They are beveled under the head for use in countersunk holes. They penetrate plywood and oriented strand board (OSB) without splitting. Threads are serrated for lower driving torque. Screws may be mildly magnetic. Length is measured from the top of the head.

18-8 Stainless Steel Thread-Cutting Small-Head
Screws for Softwood and Plastic-Wood Composites
18-8 stainless steel screws have good chemical resistance and are a good choice for ACQ-treated (arsenic-free) lumber. Also known as trim-head deck screws, they have a small flat head and slender shank to reduce the risk of splitting. The Type 17 auger point and narrow body penetrate softwood and plastic-wood composite decking material. They cut threads into drilled holes as they’re turned, so they require less driving torque and cause less stress on material than thread-forming screws. Screws may be mildly magnetic. Length is measured from the top of the head.

Steel Thread-Cutting Small-Head Screws
for Softwood and Plastic-Wood Composites
Because these steel screws cut threads into drilled holes as they’re turned, they require less driving torque and cause less stress on material than thread-forming screws. Also known as trim-head deck screws, they have a small flat head and slender shank to reduce the risk of splitting boards. Their thin head also means they won't stick out of decking, trim, and other finished surfaces. With a corrosion-resistant coating, these screws resist up to 1,500 hours of salt spray. They're green, so they blend in with most treated wood.
Length is measured from the top of the head.
Screws for Joining Sheet Metal to Wood
Able to penetrate overlapping sheets, these screws have a secure hold in wood. The hex head allows for a firm grip with a wrench, while a rubber washer provides a watertight seal. They're corrosion-resistant-coated steel to resist corrosion in wet environments and minimize reactions between dissimilar metals. Length is measured from under the washer.
Strip-Resistant Screws for Joining Drywall to Wood
Ribs under the head act as a brake to prevent over-tightening and damaging threads. A sharp point penetrates wood and sheet metal, and alternating high and low threads minimize driving torque. These screws are made from steel and have a coating that resists up to 500 hours of salt spray. Length is measured from the top of the head.
