Phillips Screws for Softwood and Plastic-Wood Composites
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 ultra-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 Square-Drive Screws
for Softwood and Plastic-Wood Composites
18-8 stainless steel screws have good chemical resistance and are a good choice for ACQ-treated (arsenic-free) lumber. They have a curved neck that sinks into material, so they sit flush with the surface. Also known as deck screws, they have a Type 17 auger point that penetrates softwood and plastic-wood composite decking material. They may be mildly magnetic. Length is measured from the top of the head.

18-8 Stainless Steel Thread-Cutting Small-Head
Screws for Softwood and Plastic-Wood Composites
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.
