About Flat Head Screws

Passivated

Black Oxide

Standard Profile

Choose these screws for their adherence to strict military standards for material and construction. They have good chemical resistance and may be mildly magnetic. Screws are angled under the head to sit flush within countersunk holes. Length is measured from the top of the head.

Screws with a 100° countersink angle distribute pressure over a wide area to prevent crushing soft materials.

Black-oxide stainless steel screws have a matte-black finish.

Passivated stainless steel screws protect against oxidation and corrosion.

Mil. Spec. Steel Phillips Flat Head Screws

Standard Profile

Choose these screws for their adherence to strict military standards for material and construction. They're cadmium plated to resist corrosion in wet environments. These screws are angled under the head to sit flush within countersunk holes. Length is measured from the top of the head. Screws with a 100° countersink angle distribute pressure over a wide area to prevent crushing soft materials.
