    Products Description


    Made from alloy steel, these screws are nearly twice as strong as stainless steel flat head screws. They're angled under the head to sit flush within countersunk holes. Length is measured from the top of the head.

    Screws with an undercut profile have a shallow head for use in thin materials.

    Black-oxide alloy steel screws have mild corrosion resistance in dry environments.

    Zinc-plated alloy steel screws resist corrosion in wet environments.
