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.

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.

These steel screws have an ultra-corrosion-resistant coating to resist corrosion in wet environments. 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. Length is measured from the top of the head.

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.

Threads change direction to cut into composites and push material back into the hole to prevent distorting the surface around the hole. Also known as trim-head deck screws, these 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. A Torx drive allows you to apply extra force with less slippage or damage to the recess. Made from 18-8 stainless steel, they have good chemical resistance and are a good choice for ACQ-treated (arsenic-free) lumber. They may be mildly magnetic. Length is measured from the top of the head.
