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.
