Steel Phillips Flat Head Screws for Wood
These screws are beveled under the head for use in countersunk holes. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Length is measured from the top of the head.
Black-oxide steel screws resist mild corrosion in dry environments.
Zinc-plated steel screws resist corrosion in wet environments.

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.

Steel Phillips Drilling Screws for Joining Wood to Metal
These screws speed installation by drilling, tapping, and fastening wood and metal in a single operation. Length is measured from the top of the head.
Screws with cutting wings drill a slightly larger hole in the wood to allow for expansion. The wings break off when they contact metal, so the screw can tap the remainder of the hole.
Corrosion-resistant-coated steel screws are a good choice for ACQ-treated (arsenic-free) lumber.

Thread-Forming Screws for Joining Wood to Metal
Thread-forming screws press threads into drilled holes for a tight vibration-resistant assembly. All are beveled under the head for use in countersunk holes. A Torx drive allows you to apply extra force with less slippage or damage to the recess. They're black-phosphate steel to resist corrosion in dry environments. Length is measured from the top of the head.

Screws for Hardwood
Also known as Type 17 auger point screws, these penetrate hardwood and reduce driving torque. They require a pilot hole to prevent splitting when used near an edge. They're beveled under the head for use in countersunk holes. Ribs underneath the head prevent loosening. Made from 18-8 stainless steel, they have good chemical resistance and are a good choice for ACQ-treated (arsenic-free) lumber. Screws may be mildly magnetic. Length is measured from the top of the head.
