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.

Super-Corrosion-Resistant 316 Stainless Steel Phillips Flat Head Screws for Wood
More corrosion resistant than 18-8 stainless steel screws, these have excellent resistance to chemicals and salt water 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.
