Low-Profile Rounded Head Drilling Screws for Metal
Also known as pancake head screws, these have a head that is about two-thirds the height of standard rounded head screws. They're designed to attach framing to metal up to 3/16" thick. They save you time and effort by drilling their own holes and fastening in a single operation. Made from steel, they have a zinc plating to resist corrosion in wet environments. Length is measured from under the head.
