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.

Flanged Rounded Head Screws for Wood


With a low-profile rounded head that’s flanged to sit flush for a finished appearance, these screws press threads into wood on cabinets, trim, molding, and light duty framing. Because they’re flanged, they distribute pressure across a wide surface, creating a tight hold and eliminating the need for a washer. The Torx drive has more points of contact than Phillips, slotted, and square drives, so you can apply extra force without worrying about slipping or stripping. These screws have a zinc plating to resist corrosion in wet environments. To prevent splitting, drill a pilot hole slightly smaller than the screw. Length is measured from under the flange.
