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.

Screw Nails for Metal, Plastic, and Plywood
Also known as round-head Type U drive screws, these fasteners drive like nails but hold with screw-like strength. Use them in drilled and punched holes. The hole size should be slightly smaller than the shank diameter.
Zinc-plated steel screw nails resist rust.
18-8 stainless steel screw nails have good corrosion resistance and may be mildly magnetic.
