Flat Head Screws for Particleboard and Fiberboard
Black Oxide
Zinc Plated
Beveled under the head for use in countersunk holes. Sharp, angled threads cut into particleboard, medium-density fiberboard (MDF), and hardboard such as masonite without splitting. Length is measured from the top of the head.
Black-oxide steel screws are mildly corrosion resistant in dry environments.
Zinc-plated steel screws resist corrosion in wet environments.
