These alloy steel screws are nearly twice as strong as stainless steel button head screws. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer. Head height includes the flange.Length is measured from under the flange.
Black-oxide alloy steel screws are mildly corrosion resistant in dry environments.
Zinc-plated alloy steel screws resist corrosion in wet environments.
