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.
Zinc-plated steel screws resist corrosion in wet environments.

18-8 Stainless Steel Phillips Flat Head Screws for Wood
18-8 stainless steel screws have good chemical resistance and are a good choice for ACQ-treated (arsenic-free) lumber. 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. They may be mildly magnetic. 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.

Super-Corrosion-Resistant 316 Stainless Steel Thread-Cutting
Small-Head Screws for Softwood and Plastic-Wood Composites
More corrosion resistant than 18-8 stainless steel screws, these have excellent resistance to chemicals and salt water 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.

Thread-Forming Small-Head Screws for Softwood and Plastic-Wood Composites
Thread-forming screws press threads into drilled holes for a tight, vibration-resistant assembly. Also known as trim-head deck screws, they have a small flat head and slender shank to reduce the risk of splitting. The sharp point and narrow body penetrates softwood and plastic-wood composite decking material. Made from steel, they have a black-phosphate finish to resist corrosion in wet environments. Length is measured from the top of the head.

Sealing Screws for Softwood and Plastic-Wood Composites
The neoprene-backed washer seals out contaminants. Also known as trim-head deck screws, they have a small flat head and slender shank to reduce the risk of splitting. They have a Type 17 auger point to penetrate softwood and plastic-wood composite decking material. 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.

Metric Steel Phillips Rounded Head Drilling Screws for Metal
Drill a pilot hole, cut threads, and fasten in one motion with these metric-threaded screws. They're self-drilling, meaning they have a pointed tip that forms a pilot hole as they enter your material. As they turn, they also cut their own reusable threads, so you don’t need to drill and tap a hole first. Designed for fastening metal to metal, these screws are often used to install ducts and other assemblies where you can only access one side. The rounded head gives your project a finished look. Made of steel, they’re strong and wear resistant. They’re also plated with zinc to protect the steel from rust and extend the life of the screws. They meet ISO and DIN dimensional standards.
