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.
