Brass screws are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. All 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.

Sharp, angled threads cut into particleboard, medium-density fiberboard (MDF), and hardboard such as masonite without splitting. Black-oxide and black-phosphate steel screws resist corrosion in dry environments. Length is measured from under the head.

A curved neck sinks into material, so these screws sit flush with the surface. Also known as deck screws, they have a sharp point and narrow body to penetrate softwood and plastic-wood composite decking material. They're made from hardened steel and have a corrosion-resistant coating that resists at least 500 hours of salt spray. Length is measured from the top of the head.

18-8 stainless steel screws have good chemical resistance and are a good choice for ACQ-treated (arsenic-free) lumber. Also known as trim-head deck screws, they have a small flat head and slender shank to reduce the risk of splitting. The Type 17 auger point and narrow body penetrate softwood and plastic-wood composite decking material. They cut threads into drilled holes as they’re turned, so they require less driving torque and cause less stress on material than thread-forming screws. Screws may be mildly magnetic. Length is measured from the top of the head.

Hang drywall to wood framing. These screws have a sharp point that penetrates drywall and a curved neck that sinks in without tearing the paper surface. Length is measured from the top of the head.

Zinc-plated and zinc yellow-chromate plated steel screws are corrosion resistant in wet environments.
