Steel Phillips Flat Head Screws for Wood
These steel screws are zinc plated to resist corrosion in wet environments. 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 Phillips Flat Head Screws for Wood
18-8 stainless steel screws have good chemical resistance and are a good choice for ACQ-treated (arsenic-free) lumber. 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. They may be mildly magnetic. Length is measured from the top of the head.

18-8 Stainless Steel Square-Drive 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. They have a curved neck that sinks into material, so they sit flush with the surface. Also known as deck screws, they have a Type 17 auger point that penetrates softwood and plastic-wood composite decking material. They may be mildly magnetic. 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.
