About Flat Head Screws

Mil. Spec. Stainless Steel Phillips Flat Head Screws

Passivated

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.
Passivated stainless steel screws protect against oxidation and corrosion.
