Steel Flat Head Screws for Plywood and Oriented Strand Board
These steel screws are zinc plated to resist corrosion in wet environments. They are beveled under the head for use in countersunk holes. They penetrate plywood and oriented strand board (OSB) without splitting. Threads are serrated for lower driving torque. Length is measured from the top of the head.
